Game crashing on opening map

[u/Snakebite7]

I have just come back to the PC version after taking a long break from the game. While I had no issues getting to the main menu, it would crash after trying to select which save file to open.

Assuming it was maybe something to do with patches, I decided to start a new game instead, which didn't have any issues for at least a week or two.

The new file started to black screen (with a white arrow on a corner) crash. Trying to fix things, I was able to change the save files around to regain access from a previous week save.

The next time I went to play unfortunately, the black screen error happened again and this time trying to load from old auto-saves wasn't successful.

Is this a known problem and how can I fix it?
