Minecraft Forge 1.12.2 crashes on startup

[Septute]

Whenever i try to start minecraft forge it always says An unexpected issues occurred and the game crashed. We are sorry for the inconvenience. It doesn't even show the loading screen or anything. It just starts and then brings me back to the launcher.

Did you read my signature?

  Reveal hidden contents

Forge Version 1.12.2-14.23.2.2629 and newer:

Post debug.log

Older versions:

Post fml-[client/server]-latest.log

 

Mojang Launcher: When using the Mojang launcher both of these files are found in .minecraft\logs.

 

Twitch Launcher: If you are using the Twitch Launcher, their configurations break Forge's log settings, unfortunately the method of getting around this is a bit convoluted:

  Reveal hidden contents

1. Take note of the Forge version the pack uses and close the Twitch launcher as well as any open Mojang launcher instances
2. Locate your Twitch Launcher installation
3. Locate the "versions" folder
4. Locate the folder corresponding to the version of Forge that your active pack uses
5. That folder will have a JSON file, in that file you will need to insert this line: "logging":{}
   • Note that at least one comma will be required to keep the JSON valid.
     • If this is added as the first line the comma will close off the line.
     • If this is at the end the previous line will need to be closed off with a comma.
     • If this is put in the middle then both commas will be needed.
6. DO NOT LAUNCH THE PACK WITH TWITCH
7. Use the appropriate script to launch Minecraft by putting it next to the Mojang launcher executable and running the script
   • These scripts use the same launch argument Twitch does, however they will not undo our changes to the version JSON.
     • Windows: Open MC Here.bat
     • Mac: [Coming Soon]
8. The log files will be in \Documents\[Twitch or Curse]\Instances\[Pack Name]\logs

 

Fallback ("No logs are generated"):

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

 

ALL LOGS: Please post logs using Pastebin or GitHub Gists(Yes, Gist will require a GitHub account. There's no harm in making one anyway.), and where possible use the upload button on these sites rather than copy-pasting the contents of the file.

Note: Gist accepts larger files than Pastebin, if logs are massive use Gist.

Do NOT use sites like mediafire, dropbox, onedrive, or, god forbid, a site that has a countdown before offering downloads.

This better?

[quadraxis]

[main/DEBUG] [FML]: Loaded 89 rules from AccessTransformer config file forge_at.cfg

 

This appears to be missing entries (I see 213 when launching 2768).

 

Can you try redownloading and reinstalling Forge?

[Septute]

I did try redownloading and reinstalling many times, with many different versions. None of them worked, it had the same issue.

[DaemonUmbra]

Try going into the .minecraft\versions and .minecraft\libraries\net\minecraftforge\forge folders and deleting the folders for that version of Forge before re-installing.

[Studucken123]

yeah mine too but even when i do all the things you said it still sais unexpected error

 

[DaemonUmbra]

Please don't hijack threads, especially old ones. If you have an issue make your own thread.
