While loading certain resourcepacks causes the game to crash while loading, this has worked in the version right before the newly launched update, the resourcepack that has been cause me problems while loading up the game is Fresh Animations 1.5 Addons, i haven't tried this with other resourcepacks but my friends have the same problem with other resourcepacks, bonus i've tried it on both my PC and Laptop getting the same result, the resourcepack is MUST for me but i really like it and i would like to continue using it on fabric it being dependent on optifine :]
