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!
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.
