It's impossible to change the screenshot folder because the folder picker won't work, you can use it and select a folder but clicking on "Select" does nothing.

Steps for reproducing this issue:

1. Open preferences, go to in-game section
2. Click on "change folder" for screenshot folder
3. Select the desired folder
4. See how the folder didn't change at all
