Screenshot of the "Unknown Error" popup
SUMMARY
When I try to render an animation, I get an "Unknown Error" popup.
STEPS TO REPRODUCE
1. Make a new file
2. Make an animation with the timeline docker
3. File -> Render Animation
4. Click OK
OBSERVED RESULT
After the program saves the frames, an error popup shows up saying "Could not
render animation: Unknown error."
The error log left where the render export path was set says:
> D:/Krita (x64)/bin/ffmpeg.exe -hide_banner -y -y -r 12 -start_number 0
> -start_number_range 1 -i D:/Mis Cosas/Imagenes/Por mÃ/frame%04d.png -c:v
> libopenh264 -b:v 5000k D:/Mis Cosas/Imagenes/Por

I made a minimal reproduction project but, oddly, when I moved it to desktop
and rendered there, it worked just fine.

I tried the same with the animation I was trying to render, but instead I got
the error again.
I also tried rendering the MRP in a location that wasn't the same as the .kra
file's, and I got the error as well.
EXPECTED RESULT
The animation renders without a hitch, regardless of location.
SOFTWARE/OS VERSIONS
Windows 10 Version 2009
Qt Version: 5.15.7
ADDITIONAL INFORMATION
I've had this issue before (https://bugs.kde.org/show_bug.cgi?id=474679) and
the assignee had successfully fixed it. Would this be a regression?
