Good evening Leti,
Tried tinkering with the monitors per your suggestions. Still had the same crash error occur with whichever one was plugged in, and both times the crash log said whichever monitor was plugged in at the time was "x: 0, y:0. w: 0"
For lack of any further ideas, I tried running the game off of the built in Intel GPU again, and the game now seems to be loading properly, with the cautionary alert that it's using the Intel GPU, rather than the Radeon GPU. If I try switching back to the Radeon GPU, it crashes again.
Not sure what you can make of that, given all drivers are up-to-date.
