I tried using optifabric 1.20.1, and it replaces all text with pure "00000000000" and I can't understand, and when I try to play it crashes

i got the same problem... and if i choose newer versions of fabric and fabric api it crashes on start with the code: The game crashed whilst initializing game
Error: java.lang.RuntimeException: Mixin transformation of me.modmuss50.optifabric.mod.Text failed

I have the same problem
