everything i have is for 1.20.1, and my forge is 1.20.1, what am I doing wrong?

What do I do if all my mods are compatible with the version I'm trying to load and still get error code -1?

[AzaGorod]

What if one has only 1 mod (optifine) mode for the correct version (1.20.1) but still get exit code -1 on save load.

Everytime I try to run a 1.19.2 modpack, I keep getting Exit Code 1 and saying "Could not create the Java Virtual Machine". I've tried reinstalling the modpack, the java version, running the java version command in command panel, and even adjusting the RAM. Nothing Works

When I try downloading any mods beside the mr crawfish furniture mod I get a whole bunch of errors messages. I can load up my game but can’t play it does anyone know what too do. I am playing on 1.19.2

i need help, and no one has aparently a solution for this in yt, when i create a new world everything is fine till it suddently says:

Failed to connect to server (playing singelplayer not in an actuall server)
internal exeption: And unexpected criticall error was encountered.


_ i tried playing whitout any mods, still had the same issue, then i went back an update of the forge version that's still on 1.19.2 but still had the same msg pop up. genuetly don't know what to do other than give up on mods

The weird thing is im experiencing this but all my 4 mods are 1.19.2 and my forge is 1.19.2

Thanks, I didn't realize the Optifine version I already had installed was the wrong version until watching this

[tuqueboo]

Hi, I'm still getting error code 1 after running MC Forge 1.19 with only a few 1.19 mods, still happening - makes me wanna quit Mc

[AlaskaWild]

Did not fix my issue. I am running the latest version of Java, Minecraft, Forge, etc. ZERO mods in my %appdata% .minecraft folder.

[Obongus]

well i dont have any outdated mods and its still crashing with exit code 1

[NotLoopyy]

For me this didn't work. Thanks for the tutorial but I think my minecraft just hates me. I've tried literally everything. The only thing I haven't tried is deleting minecraft and reinstalling it. Which I am too lazy to do so I gave up.

I can't use optifinw but all other mods work perfectly fine in 1.8.9 can you help?

[Padre-Alvero]

My problem is with optifine. I got the same version that’s supposedly compatible with forge, but when I put optifine in the mods folder for versions like 1.20 for example, it crashes, same with when I use optiforge in 1.16.5. Gives me exit code 1

[gonzaabbas]

my problem is that it only crashes with the hostile worlds mod in version 1.7.10

[mishamoo]

what do i do if my minecraft folder doesnt have a folder called “mods” in it. im lost.

[kanuan]

does not work? like my mods are updated my java is the latest and none of my mods are incopatable with each other and when you said "go to the windows search bar, type run and open the run aplication" i dont have that. I now have read the description and open the link but the problem is still there even doin all the "fixes" of the website
