On Windows 11.  
Out of the blue I notice an app I blocked from accessing the network was online... I proceeded to block it and investigate.  EVERY SINGLE entry was gone and completely reset.  This has happened before but far enough apart where I kinda blew it off to a glitch... WTH is going on?  Those were a lot of frickin entries to suddenly have to do it all over again... Does Bitdefender at least keep a backup of these settings somewhere?  WHY does this keep happening????????
