Real time protection blocking everything

I've had an M5 multi-unit Deco M5 system for several years without a problem. A couple of days ago I upgraded to the latest firmware version 1.9 and now every single device in my house gets blocked by the real time protection system. Rebooting Deco does not fix the problem. The only thing I can do is to turn real time protection off.
Is there a fix?

Hi, would there be any security attack notifications on the Deco APP, such as:
https://community.tp-link.com/en/home/forum/topic/837864?replyId=1605918
If yes, can I have some screenshots here?
It is also suggested to test the beta firmware shared above to see whether it helped or not.
Wait for your reply.
Best regards.
