Weird rare mine bug on co op console?

Hi, I’ve never seen anyone mention this before so I thought I’d ask because it’s becoming very annoying.

Semi-regularly, like enough to be annoying, when playing co-op on xbox with my partner (I don’t know much about consoles but I think it’s like the newest most up-to-date xbox) the mines kinda like,,, freeze?

I don’t really know how to describe it, I’ll take photos next time it happens but basically everything sticks- the monsters stay where they are and don’t attack, the ‘whoosh’ lines made by swords and pickaxes stick on the screen so it fills up with weird white cloud things, anything dropped can’t be picked up into inventory (not full, even things that are already in it like stones), and then it’s basically impossible with everything sticking and moving really slowly to find the ladder down, meaning the whole thing up to then is pointless because to ‘un-freeze’ it the player has to leave the mine and obviously this resets the progress that day.

It doesn’t matter if we’re both in the mine or just one of us, it’s happened either time. I actually think it’s only happened to my partner, it’s a co-op farm but it’s ‘his’ save if that makes sense, as in he was the one to set the farm up. He doesn’t play on his own so I don’t know if it’s just a co-op thing or a more general thing. It's only happened since the 1.6 console update.

I’m a PC player, I just play console with him, so I don’t know anything about what it might be/how to fix it and i’ve never seen anyone mention this issue before.

Thanks !!
