CTFMON hard errors when combining RemoteApp & Remote Desktop

Ah, never mind, it appears that combining RemoteApp and Desktop in the same host pool for the same user is not supported.
See here: https://learn.microsoft.com/en-us/azure/virtual-desktop/terminology#app-groups
We don't support assigning both the RemoteApp and desktop application groups in a single host pool to the same user. Doing so will cause a single user to have two user sessions in a single host pool. Users aren't supposed to have two active user sessions at the same time, as this can cause the following things to happen:
The session hosts become overloaded
Users get stuck when trying to login
Connections won't work
The screen turns black
The application crashes
Other negative effects on end-user experience and session performance

jfdoyon that is interesting! We appear to be having pretty much the same symptoms, but without the desktop involved. Win 11 23H2 as well using Entra SSO. Single host with one published app. Most users are fine but one account gets to "Preparing Windows" and then changes to a permanent black screen, and that is a local admin account. The first logon for all users takes about 5 minutes and pauses at the same place (which may be OneDrive so we are removing that as a first step). We do have a desktop published to the same host, but only for our test user account to use if/when needed. Ctfmon.exe and the Search service are constantly logged for crashing. Did your problems go away when you removed the desktop?
