I really don't understand what is happening, what is the incompatibilitie here, but the game always crash when y try to use this mod on my current gameplay of 1.12.2:
crash-2025-07-22_06.44.03-client.txt

The crash report show a prev version, i tried to see if the issue could get fixed using an old version, but nothing same error as new updated. Someone could tell what is the issue?

Looks like the Mixin loader is having issues. Could be a conflict with the bundled version in the 1.12.2 build and mixinbooter. Try removing mixinbooter, otherwise not sure. The 1.12.2 version is currently not supported, so either it works, or it doesn't.

Sadly can't remove Mixinbooter since is needed for Lootr, but i see
is shame, i wanted to use this mod for 1.12.2
