[1.12.2] I have no experience with adding my own selection of mods to the mods folder. It keeps crashing. Help?

This is the first time I have ever added my own mods to my worlds. I usually just download modpacks from different launchers. I decided to try it out. When I hit play, the screen will do it's usual loading, get through a bit of the "loading - constructing mods" phase and then crash. I have no idea how to figure out what is wrong. Its says:  

The game crashed whilst initializing game
Error: java.lang.NullPointerException: Initializing game

 When I look at the crash report it says this:

Big crash.txt

    Where are you getting your mods?

    This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

     

    As the most common issue I feel I should put this outside the main bulk:

    The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

    If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

     

    For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

    Spoiler

    Logs (Most issues require logs to diagnose):

    Spoiler

    Please post logs using one of the following sites (Thank you Lumber Wizard for the list):

    https://gist.github.com/: 100MB Requires member (Free)

    https://pastebin.com/: 512KB as guest, 10MB as Pro ($$$)

    https://hastebin.com/: 400KB

    Do NOT use sites like Mediafire, Dropbox, OneDrive, Google Drive, or a site that has a countdown before offering downloads.

     

    What to provide:

    ...for Crashes and Runtime issues:

    Minecraft 1.14.4 and newer:

    Post debug.log

    Older versions:

    Please update...

     

    ...for Installer Issues:

    Post your installer log, found in the same place you ran the installer

    This log will be called either installer.log or named the same as the installer but with .log on the end

    Note for Windows users:

    Windows hides file extensions by default so the installer may appear without the .jar extension then when the .log is added the log will appear with the .jar extension

     

    Where to get it:

    Mojang Launcher: When using the Mojang launcher debug.log is found in .minecraft\logs.

     

    Curse/Overwolf: If you are using the Curse Launcher, their configurations break Forge's log settings, fortunately there is an easier workaround than I originally thought, this works even with Curse's installation of the Minecraft launcher as long as it is not launched THROUGH Twitch:

    Spoiler
    1. Make sure you have the correct version of Forge installed (some packs are heavily dependent on one specific build of Forge)
    2. Make a launcher profile targeting this version of Forge.
    3. Set the launcher profile's GameDir property to the pack's instance folder (not the instances folder, the folder that has the pack's name on it).
    4. Now launch the pack through that profile and follow the "Mojang Launcher" instructions above.

    or alternately, 

     

    Fallback ("No logs are generated"):

    If you don't see logs generated in the usual place, provide the launcher_log.txt from .minecraft

     

    Server Not Starting:

    Spoiler

    If your server does not start or a command window appears and immediately goes away, run the jar manually and provide the output.

     

    Reporting Illegal/Inappropriate Adfocus Ads:

    Spoiler

    Get a screenshot of the URL bar or copy/paste the whole URL into a thread on the General Discussion board with a description of the Ad.

    Lex will need the Ad ID contained in that URL to report it to Adfocus' support team.

     

    Posting your mod as a GitHub Repo:

    Spoiler

    When you have an issue with your mod the most helpful thing you can do when asking for help is to provide your code to those helping you. The most convenient way to do this is via GitHub or another source control hub.

    When setting up a GitHub Repo it might seem easy to just upload everything, however this method has the potential for mistakes that could lead to trouble later on, it is recommended to use a Git client or to get comfortable with the Git command line. The following instructions will use the Git Command Line and as such they assume you already have it installed and that you have created a repository.

     

    1. Open a command prompt (CMD, Powershell, Terminal, etc).
    2. Navigate to the folder you extracted Forge’s MDK to (the one that had all the licenses in).
    3. Run the following commands:
      1. git init
      2. git remote add origin [Your Repository's URL]
        • In the case of GitHub it should look like: https://GitHub.com/[Your Username]/[Repo Name].git
      3. git fetch
      4. git checkout --track origin/master
      5. git stage *
      6. git commit -m "[Your commit message]"
      7. git push
    4. Navigate to GitHub and you should now see most of the files.
      • note that it is intentional that some are not synced with GitHub and this is done with the (hidden) .gitignore file that Forge’s MDK has provided (hence the strictness on which folder git init is run from)
    5. Now you can share your GitHub link with those who you are asking for help.

    [Workaround line, please ignore]

    If you still have issues then, post updated logs.

    What if I can't find an official source? Like for Industrial Foregoing

    Yes. CurseForge is almost always the official source for mods.

    How do I know if it's not? What if there is a website for the mod? Should I get it there?

    If the mod is on CurseForge it's fine to download from there.

    Official websites for the mods are also fine (if they are actually official).

    Would it be okay to download a mod if it was never updated to a newer version and somebody other than the original creator updates it?

    If they have the permissions to do so, it's fine.

    1 More question for now. Do some mods work with new versions of minecraft? Like a 1.11.2 mod working with 1.12.2 forge?

    What about shaders?

    Now it says i am missing dependencies like endercore 1.12.2-o.5.58 or above and cofhcore 4.6.0. Are those just other mods that these need to run? Do I just download them like any other mod?

    I downloaded all the mods and their dependencies from curseforge and official websites and now when I launch the game, the loading screen wont even show up. The launcher will close like normal, then pop back up a couple seconds later with the message "An unexpected issue occurred and the game has crashed. We're sorry for the inconvenience." When I click on "View crash report", nothing happens. What do I do?
