I believe the issue stems from your account management system failing to fully bypass Facebook's scrutiny, resulting in mass account lockouts. You should review your anti-detect browser and proxy setup.

Feature restrictions without a clear reason can cause serious confusion especially when established groups suddenly become inaccessible.
Hopefully Facebook provides better details when these actions occur.
