Crashes when trying to open encoder settings

[markovcheney-gif]

What were you doing when VidCoder crashed?

Worked fine prior to update. After update, crashes every time

Crash details

[markovcheney-gif]

selected a different preset and now it does not crash, even when selecting the previous preset again. guess the issue is resolved

[RandomEngy]

This should be fixed in v12.22.

[markovcheney-gif]

It just updated to 12.22 and it is still crashing
