Why not pin this to issues or write the solution in the readme, I've noticed that a lot of people still don't know the solution, and many more don't know how to solve it from the command line.

My little suggestion.

The problem is when I add Additional command arguments, I get this endless encoding processing
This is what I used:
-f dshow -i audio="Analogue 1 + 2 (Focusrite USB Audio)" -filter_complex amix=inputs=2:duration=longest

Maybe you have a corrupt ffmpeg installation? (Other SW may want to overwrite ffmpeg you already have.)
Do check with:

where.exe ffmpeg.exe
cd C:\Program Files\ShareX\ && ffmpeg -list_devices true -f dshow -i dummy

Not sure what is the issue, if I remove the additional argument, then it works fine
