It's been 8 months and you still haven't fixed this issue. OBS it is!
Hi there, sorry for the late reply. If you're willing to give it another shot, we can give you more assistance!
Error 11 is based around having the location where your videos are trying to be saved be invalid. With that being the case, have you tried changing the save location?
If this issue becomes more complicated than just simply changing your save location, we can help you create a ticket to hopefully get more information and see what might be happening.
