Wow! I just submitted a ticket to support because I'm also at my wits end about it with my Cosmos Elite, So I don't know if it has to do with it being wireless unfortunately. It doesn't matter what game I try, at some point it will inevitably freeze up. Just like you, I could go a week without it but then it'll plague me for an entire days session! It happened when I had an i7-4790, GTX 1070, and 16GB DDR3 on a HDD, and it still happens with my i9 10900k, GTX 1070, and 32GB DDR4 on an M.2 SSD. I assume, it'll continue when I get a 3080.
