Gifski only opens as a background process on Windows 10

[Weisswelt]

Gifski had been working for me just fine until two days ago. When I tried opening it, the program window appeared for less than a second and then disappeared, only to check Task Manager and see it running as a background process.

I tried reinstalling Gifski, restarting my PC and even booting into Safe Mode, but none of these things worked.
