After the 1.17 update for enhanced celestials the LightmapTextureManagerMixin doesnt seem to fix the compatibility issues anymore and this is the crash report below. After removing enhanced celestials and keeping optifine on the game runs with no issue and same for removing optifabric and leaving enhanced celestials on so besides that theres no compatibility issues with the other mods listed in the crashlog
