I'm not using regular Minecraft, i'm using a 3rd party program

I googled 'Multimc org.lwjgl.LWJGLException' & it came up with quite a few results.

Looking at a few - most seem to indicate a problem with 'old Intel GPU', JAVA and Win 10

The issue @jikuja linked is Intel HD 3000 and older Intel integrated GPUs not being supported on Windows 10 and people upgrading even though they have unsupported hardware - mostly unknowingly.

this is most likely some sort of bad interaction between Minecraft, java 8u60 and Windows 10. Try downgrading java.

Have a look at this page might help - it basically says that you either get updated driver for your card - preferably NOT through Windows update but from the manufacturer or downgrade your Java, although this does refer to the official launcher & not Multimc - it might still be relevant.

Incidentally - does minecraft run OK with the official launcher - or does the same thing happen ??

Also - did you try starting up with a vanilla version before attempting to start up the Modded 'forge' version ??

@CannonFoddr

Ill try downgrading my java, and yes my regular minecraft still works

If you can't resolve it, you should join the MultiMC Discord Help server or the MultiMC Subreddit and get help from them. The creators and developers are all there. Though it does look to be that it isn't a MultiMC launcher problem.
