I recently discovered the windows 10 photos app and have been using it to edit videos made with w10 camera app (through my webcam). It is a great app and very intuitive, however lately alot of the video clips I trim out of videos made with my webcam using the w10 camera app come out garbled. The audio is sped up and the video is too. I can't tell what is causing this. Sometimes when I reboot it fixes the problem, only or it to return a couple of edits later.

I can't find anywhere using google search anyone having a problem like this.
