Operating System​

Windows 10

What Happened​

What Was Expected​

The window would remain visible

Reproduction Steps​

1. Launch Game
2. Click KSA window

Reproduction Rate​

Every time

Additional Info​

• Video/Screenshots:
  Apologies for recording monitor with phone, the screen recording would crash when attempted
• Other Notes: Multiple other users in KSA discord that run RX 580s reported the same issue

Getting similar effects on win11. Integrated graphics from a 13700H.
Will eventually crash after flashing and then staying black for a while. I attached a crashdump. The screen recording didn't actually show the issue.

My problem was fixed by going into settings.toml and changing "fullscreen" to "windowed". Wish it was possible to change that in the initial settings menu instead of having to go text edit a file
