Hi,
The same it's happening in the domain that I work in everyday. Those computers or virtual machines in which Windows 11 is being installed are inaccesible through Remote Desktop connections after installing Eset Endpoint Antivirus on them. On the client side of EEA, it can be seen those blocked RDP incoming connections under Setup --> Network --> "Resolve Blocked Communication" section. Sorry for not having a solution yet, I am trying to find one. I just wanted to inform that there are more cases with the same situation.
