I use CurseForge to load my mods. I have disabled Indium, Iris, Isometric Renders, Lithium and Sodium, all of which say they're incompatible with OptiFabric when I tried booting it up originally (except Indium, it just disables along with Sodium). I now get an Exit Code 1 error saying that Minecraft crashed, this time without saying it has any incompatible mods, and I'm not sure what to do. I isolated it to only OptiFabric having an issue by keeping Sodium, Lithium, etc. off and turning off OptiFabric and launching Minecraft. It launches and plays with no problem, but turning OptiFabric on gives me the crash and error.
I have linked a CurseForge export of my mods as well as a screenshot of the error.

Since that's a modpack, fixing every single incompatibility would take too long. If Better MC spoon-feeds you Optifine replacements just use them instead of disabling them and adding OptiFabric.
