Remoteapp login application rdpinit.xed causing high cpu

Question

I have a remoteapp server running on Azure, the server is Windows Server 2022, we are using remote desktop gateway for the users to connect, on the workstations we used the RemoteApp and Desktop Connections from the control panel to setup the connection, the instance size is Standard E8ads v5. We have a domain controller and a SQL server on the Azure tenant that work with the app server. We have a VPN setup between the customer building and the azure network. There are maybe 10 applications published however only about 4 get used on a regular basis. The users are complaining that the server locks up, which it doesn't, the CPU is just at 100%. The process that is killing the server is "RemoteApp Logon Application", which seems to be working with "rdpinit.exe". There could be 20 to 25 users signed in working, and 6 or 7 will have these processes using 13 to 17% of the CPU. The amount of RAM being used hovers around 50%, and the disks are hardly working.

It will settle down on one or two of the users and then jump to another user that will have this process start chewing up the cpu, eventually it will settle down but will randomly start all over again.

What is this process, what would cause it to use that much cpu? The users are already logged in so the name of the process doesn't seem to make sense. I have not been able to find anything on it searching the web. I need to get this resolved as it makes the server useless when it happens, which is far to often.

This server was created a few months ago, there are no viruses on it as one thread I found was trying to imply, but that was a windows 10 computer which is not relevant. Any help would be appreciated.
