The crash log at paste.ee/p/lGgsm shows a conflict between TabbyChat 2.3.4 and the 5zig mod. Start by reproducing the crash in a Minecraft 1.12.2 environment with both mods. Examine the stack trace to identify the conflicting class or method, likely in the mod loading or initialization phase. Check the mod's source for compatibility patches or mixin conflicts, and see if the old 5zig mod version works as a reference.
