RemoteApp crashing on Windows Server 2025 with Windows 11/10

Hi!

I'm currently having some troubles with the following scenario:

SRRDS01 - Connection Broker, WebAccess, SessionHost, Licensing

SRRDS02 - SessionHost

This two servers have a RemoteApp collection where both are session hosts.

Some users are reporting that the RemoteApps are crashing. When this happens, on the client computer I can see the event below.

Faulting application name: mstsc.exe, version: 10.0.26100.4202, time stamp: 0x8ee6b89b

On the server, I can see the following events:

I have tried disable UDP on the client but that didn't make any difference.

Does anybody has had this problem before?
