Something is deeply wrong with the compatibility of the newer Paradox games. I have CK3 and Vic3 and have played them in the past without issue. For the last month at least, whenever I launch the games they crash my entire PC after a random amount of time. Sometimes it's seconds after loading a save, other times I can get maybe 10- 15 minutes in before a crash. I do not have any such problem with Stellaris, EU4, HOI4, or any non-Paradox game. I have verified the game cache multiple times and do not have mods.
