It's Actions & Stuff by Oreville Studios
Oh, the problem was solved after I removed the resource packs activated, thanks for helping me with this problem, I thought it was a problem that was in the game version itself, but it was just the resource packs, thanks for the help
I wanted to use 32x resolution, which keeps the original texture of the blocks and adds the mob animations, but when I enter the realm after updating the resolution, it seems to be reset to 16x (the original resolution) and if I go back to see what resolution was set, it hasn't changed
