I should also note that, regarding the lack of error messages after each crash, I also tried to look through the event viewer logs to see if I could find anything of note.

I took a note on the time of each crash, then tried to check for any events with the same timestamp. It turned up nothing at those timestamps. So no crash logs, no event viewer events. Just ends up closing.

I also should note that I can't attempt to do this anymore as the game doesn't even crash after Support asked me to manually delete the local save data - instead the game sits unresponsive until it's manually ended now. For reference, this is what it looks like when I press Play now.
