I decided to install the Optifine on Fabric for version 1.20, I downloaded the Optifine from the official website preview_OptiFine_1.20_HD_U_I5_pre5.jar . When I started Minecraft it crashed with the error window Fabric loader 0.14.21

java.lang.ExceptionInInitializerError

Remove ReplayMod, its broken with Optifabric, and Choco or someone needs to supply the fixes.

That doesn`t help
