I can't say I've tested Forge with Realms.... Please provide your debug log

Delete it, it's used for setting you want to apply to every Java process and usually when I see people mention using it they put in settings that shouldn't be global

Thanks to your images in another thread I think i know where the issue is: Why do you have JAVA_OPTS set, and why does it have that value?

Please provide the debug log

What happens if you launch it through cmd? (java -jar [forge].jar)

Did you delete anything in your versions folder?

Can you provide the file I asked for?

What do you mean “the other options don’t work”? I am not downloading a file from a site I’ve never heard of...

You probably have a 32-Bit JRE installed, you need 64-Bit

I can't read that language, can you provide your debug log?

That's a 404 from a site I don't recognize, please use Pastebin or GitHub Gist.

Windows is hiding file extensions from you, you need to include the .jar at the end of Forge's filename when you launch via cmd or batch

Please read the EAQ or my Signature and provide your debug log

Update Java to Java 8 u201/u202

Please provide your installer log

Using this version of Forge alone, I do not have this issue. Are you sure you have cheats enabled?

Optifine has not been updated to work with Forge's new loading system yet and Forge does not provide support for Rift mods. Also that log appears to be from a real 1.12.2 run, not a bug in your 1.13.2 run.

The entire loading process has been changed, @Instance no longer exists, you can easily set your own instance variable in your mod's constructor (this is also where you'll want to add non-static event handlers to the event bus).

How did you install Forge?

If there's no Minecraft crash, check Minecraft's folder for a file with a name along the lines of hs_err_pid<numbers>.log if there is a file like that then it is a JVM or native crash, and sucky intel drivers are the usual suspect in that case.

microdumps being disabled sounds like something that would be logged but not the cause of the issue, I'll split these messages into a new thread so we're not mucking up this one.

If you're crashing, please provide a debug log. JModder, it makes no sense that you would be unable to use javaw, but if you don't have internet on your PC you can't easily share a log, can you? Edit: Separate issue, I've split the messages about this into their own thread.

How did you add the 1Gig argument?

Unfortunately pretty much all development assumes you can connect the machine to the internet at least once.

You are comparing learning programming and the conventions of a framework that can be done for free if you just devote some time, to studies that are funded by major corporations.
