Today optifine updated with a preview version for 1.19.3 and a full version for 1.19.2 (OptiFine_1.19.2_HD_U_I1_MOD) so.. probably .3 wont work too

I don't know when will this incompatibility be updated and fixed this incompatibility. 😟 I hope it comes out soon.

I confirmed I could launch Minecraft with OptiFine_1.19.2_HD_U_I1 + Optifabric 1.13.16 + Fabric API 0.73.0+1.19.2.
So it should be a mod compatibility issue. Please attach the latest.log.

1.19.3 has a different story; Mojang changed many things in incompatible ways, including rendering-related ones. Developer's work will be required for migration. By the way, we already have the 1.19.3 issue, so we should continue there.
