I have tried to delete the MS Store from the list of apps being "allowed" to use my camera. Unfortunately, bitdefender keeps adding it back in and I receive a notification multiple times a day that it has been added back to the app list.
Hello @bbd313,
Check if this setting is enabled and see if it makes any difference turning it off. The webcam protection has an interesting feature where if most Bitdefender users consider a popular app as being harmless, then its access to the webcam will be automatically set to Allow. If a popular app is considered dangerous by many users, then its access will be automatically set to Block. You will be informed each time one of your installed apps will be listed as blocked by a majority of Bitdefender users. So maybe this setting overrides your setup in this case.
Otherwise, If reinstalling Bitdefender doesn't solve the issue, I think it's a task for the Support enginners to investigate further.
Regards
