[SpaceWalkerRS]

Hi, it looks like you are running a Gen1 instance with a recent version of OSL. Any version of OSL since 0.17 require a Gen2 instance.

[helpimnotdrowning]

Gen1 instances for PrismLauncher are generated by default by the GUI installer. How would I generate a Gen2 instance?

edit: with the Native installer; the Java installer refuses to run since I have never used the stock launcher

[SpaceWalkerRS]

You can use the CLI. There's more information in the wiki article: https://wiki.ornithemc.net/wiki/Installing_Ornithe

[qoinex-dev]

So would CLI installation fix the issue? I don't know what a Gen1 or Gen2 instance is.

[helpimnotdrowning]

yes, from what i gather a Gen1 instance is now the "old" type of Ornithe, and Gen2 is some new form. the GUI installer only creates Gen1 instances for some reason, but with the CLI you can create a Gen2 instance

you can find the correct command for your launcher here (official or Prism): https://wiki.ornithemc.net/wiki/Installing_Ornithe ,
then append --gen 2 to the command to generate the correct profile
