I'm having a similar issue. Something that helps me is disabling fullscreen in options.txt. It's less-than-ideal, but it stops the game from crashing.
Thanks, I'll take a look at that.
Confirmed for baby foxes in 1.14.3. This needs to be reopened, it's a big problem again!
Same Problem! Although, It launches the game successfully.
Can confirm, it also seems as if both the placing and digging animations are now the same animation, compared to 1.21.1 where they were different.
