We are in the testing phase of upgrading to server 2022 for our RD Session hosts. We are experiencing random frozen sessions about 1-2x per day per user and the only way to unfreeze is to disconnect from the session and reopen it. The disconnect code that's shown in 'Microsoft-Windows-TerminalServices-LocalSessionManager/Operational' is 2147942464. The collections with 2019 session host servers are not experiencing this issue.
The connection broker is still 2019 so I'm wondering if this is a compatibility issue.
