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.

Ted Brister 1 Reputation point2022-02-17T16:02:43.43+00:00 I'm having the same issue. I have a clean install of server 2022. My RDS is a VM running on a server 2022 Hyper V host. Never had any problems on server 2019 VM.

Michael Anderson 0 Reputation points2023-03-23T20:41:48.44+00:00 Had same issue. For us it was MS Teams, once we got rid of it, everything was fine. It's been a while but I think the issue is that it was writing into the registry 1000's of records at a time, there was this tread that talks about the how to fix using the registry :

When we are using Chrome, explorer.exe is at 6%.
And chrome is freezing when opening a new tab or when clicking on a website.
When explorer.exe is killed, no more issue. -

Michael Anderson 1 Reputation point2022-05-03T23:02:03.937+00:00 You guys ROCK!!! This has been very hard to identify.
Deleting everything under HKLM\SYSTEM\Software\Microsoft\TIP\TestResults\ fixes this freezing issue (which took 10minutes to complete removal).
Immediately new entries were piling up.
Like others suggested above, remove Full Control permission for SYSTEM AND Users from the TestResult Node (so they only have read).
We're going to take an additional step and uninstall Teams and Office Suite. We've put libreoffice for users that need to open word and excel docs.

Master Control 1 Reputation point2022-12-01T13:39:50.287+00:00 This occurred with us on a MS 2022 Server and when we spun up a MS2019 Server we had the same issue with RDP sessions having latency. It was very random and weird behavior because it wasn't consistent at all. Some RDP sessions would have no issues and at the same time other sessions would freeze until you disconnect/reconnect, or the latency was so bad the RDP wasn't usable at all. All connections were through VPN (both site to site and web VPN). It's believed the UDP setting/traffic was interfering even though all packets & traffic looked good through the VPN and there wasn't anything blocking the UDP traffic. The issue was resolved by turning off UDP on Client through group policy.
On PC: Open the RUN dialog > gpedit.msc > Administrative Templates > Windows Comonents > Remote Desktop Services > Remote Desktop Connection Client > Turn Off UDP on Client
and enable it and add any notes you wish
On Server/Domain Controller go to GP Managment: Administrative Tools > Group Policy Management and create a group policy under the Domain
