Twitch will not launch mods

[Marshen]

Hello! I have been trying to figure this out for hours now and i decided its just best if I ask for help. Everytime i try to launch a mod through the twitch app I am met with this crash report... "Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=256m; support was removed in 8.0
Error: Could not find or load main class E"

 

I could really use help and please try to explain it as simple as possible and tell me how to fix this :( I am currently trying to play All the Mods 4.

 

Tysm!

I am using java Version 8 Update 251 I just deleted java and redownloaded it and it is still giving me the error.

Oh pfft, I misread, my bad.

What's your full configuration with program/vm arguments? It's having trouble finding the main class, which is an issue I've never seen someone have before.

How do i find those? is it in the minecraft launcher?

 

This is what it says in the launcher log

I don't use the Twitch launcher so I'm kind of just winging it here. In your settings for the Twitch launcher, there should be a Minecraft section. Down at the bottom is where I believe the java settings are.

From the sounds of it, I'm skeptical that that's where the problem is, but it's worth checking.

Edit: Ooh, didn't see your stealth edit.

Yes I have the option between Java: 1.8.0.241 (64 Bit) and Java: 13.0.1.0 (64 Bit) and i am currently on the  Java: 1.8.0.241 (64 Bit

Wait i think i figured out the problem. I accidently typed "E" in the Additional Arguments of the java settings. Everytime i try to delete it i change the tab and go back and it is still there.

 

I dont know how to make it stay deleted

It sounds like there's multiple problems at this point, the error in your edited post is different from the one in your original post.

If you can't get the arguments to stick, look around for a "Repair Minecraft" button somewhere. I don't know where it is, might be on the modpack's page, probably in one of those "..." menus; it should at least fix the FileNotFoundException.
