Disable mode does not work, slamdown. The only way to get webcams working again with 18.0.2 is to uninstall Avast or revert obs to 18.0.1.
If this is a bug, hopefully they will fix soon.
If this is an intentional design decision on their behalf, to block webcams and video devices of non-whitelisted programs (which it's looking like, because 18.0.1's exe works fine), I'm going to be very upset. According to that thread, it's causing chaos everywhere. If they don't fix this issue, I'm going to have to start recommending people install other anti-virus software, because I can't make releases otherwise. I unfortunately have to have a contingency plan here. Hopefully they'll fix it, and I'm cautiously optimistic that they will come to their senses and fix it. I don't want to ever have to say "hey people, don't use this anti-virus software" -- it just sounds bad for a developer to ever have to say. Not just bad, ridiculous. People then misunderstand it or become suspicious or something.
