I played the demo on the Steam Deck. I enjoyed a lot but it did crash a lot. I definitely plan on getting the game but I do hope it gets some stability support as it really needs it.
Interesting, I don't own a deck so I've never had a chance to test it on there. Did the crashes happen at any specific time or were they random?
It was random. Every few minutes it would crash. Even when trying different compatibility layers.
I don't have a Steam deck, but I played on Linux PC and never had a single crash. So whatever the cause is, it's not endemic to Linux.
