So this bug is going around for a while since i downloaded 1.17.1 or any above when you play minecraft it lets you play in a world for a couple of time and randomly freezes even at the title screen or any other screens. playing on this bug could be annoying an example is when i was playing with my sister she was looting a ocean ruin and i protected her by killing the nearby drowneds but at that moment i my minecraft froze and she could not loot it and we died 

but my pc did not freeze i could still press alt + f4 to get out so i found this as a bug i currently dont have any videos or photos about it

try to fix it as soon as possible Mojang Studios
