Forge not found? Crashing on launch, using prism, error code 2, no mods

[rynamo]

the full console text from the most recent attempt: https://pastebin.com/RWPG6Tug

this is on a clean new instance of 1.21.4 in prism.

- old installs work. i haven't tried editing them.

- changing the minecraft version works, only for 1.20.2. any mods for anything other than 1.20.2 will cause the game to fail to launch.

- i tried switching launhers to neoforge and prism, and got a similar result.

i'm fresh out of ideas.

Try using the vanilla launcher, if it fails post that log

so, say i haven't played vanilla minecraft in a very long time, and i can't find 'minecraft' in my applications folder (i'm on mac), and i've since forgotten what i used to use to access vanilla minecraft. how would i find it?

i did try with a new download of vanilla, and it launched fine.

Then I would say the issue is most likely prism launcher, if using the vanilla launcher works.

Perhaps there is an update for it or something?

[eMigrowsLy1]

the problem is most likely in the settings or incompatibility of Prism with Forge 1.21.4

[rynamo]

i did make sure prism was updated, and it is. the issue isn't just with 1.21.4, it's with a bunch of other versions, except 1.21 and 1.20.2.

So I just noticed near the top of the log it says "Launched instance in offline mode", does that mean it is bypassing Minecraft account authentication?

If so, that is probably the issue.
