Hey Steve, you might not see this, but has the dev team looked at the possibility of something backend/server side leading to the crashes? We have a decently active pubg discord, and we have been having multiple players crash at the same times in a game. We all have high end pc's, and 2 players in our main group are software/game developers, so I can't imagine all of us somehow simultaneously having OS issues.
Last night playing squads, our BDRM driver (playing on a thread ripper, 256gb ram, nvme drive, and 3080) says "my frames are dropping BAD" and within q5 seconds he has crashed. 10 seconds later a 2nd player on our team crashed in the same way. We had a 2nd squad of 4 playing in the same game (we matched in together), and they had 2 players crash to desktop at almost the same time in the same game.
I have a very hard time believing that 4 players in the same game can all have OS issues at the same time.
