I'm just looking for a way to play 1.20.1 (ideally 1.20.4) with Bobby and Optifine. Launching with my mod loadout without Optifine doesn't crash but blocks me with the message that OptiFabric doesn't detect Optifine. Launching the game with Optifine included crashes the game and gives me an error with Exit Code: 1. Would appreciate help fixing this.
My Mods:
Fabric launcher 0.14.25
Fabric API 0.85.0
OptiFabric 1.14.3
Optifine 1.20.1 HD U I6
Bobby 5.0.1

That does work. Unfortunately the same problem occurs with ver. 5.0.0 of Bobby as well. I might need to try an alternative for shaders. Thanks for the suggestion.

You're welcome and good luck

Try running it again without bobby and see if it still crashes.

Please close your ticket.
