This started whenever I upgraded to the latest version. The screen spazzes out for a second, looks like it toggles between the menu and the game window several times, and then RA freezes up. Unfortunately, the log contains no useful info 
The screenshot image that is taken is always just an all black image.
Any guesses?
does it still do it if you move your config somewhere else temporarily?
reverting to the default config solves it!
I think I just did this:
-enabled hard gpu sync,
-enabled run ahead w/3 frames,
-enabled integer scale
-set a custom aspect ratio of 1494x1120
-changed set the file browser directory
-set video driver to vulkan
does anything stand out?
Edit:
nevermind, it’s vulkan
