Minecraft wont close and is stuck on a loading screen

I was checking out the new snapshot on a single-player world and got this thing where i get stuck on the saving world/loading terrain sometimes when i leave/join any world (including multiplayer) i tried to close it in every way but it didn't work and i cant close it no matter what i do this mostly happens when i lag alot but please try to fix it (this time it might've been the sniffer egg) but honestly i don't know why it happens and i don't know how many others have had this and nobody else i know actually had this happen (it is stuck on the shown picture) (and it is for 23w12a and down to 1.12.2 discovered so far from me)
