Zoom no longer works with OBS virtualcam

Until last week zoom worked perfectly well with OBS virtualcam. Today it didnt detect the input feed from OBS virtualcam any longer. Skype still works with OBS virtualcam so the issue must be on zooms end.

I found some threads about 1,5 years old about this kind of problem but the last word in these threads was that newer versions of zoom had solved the issue. 

Has there been a recent update that might be causing this issue?
