Issue with XRDP on Ubuntu 24: Connection Fails on First Attempt Post-Restart

[Mudassar000]

I'm encountering an issue with XRDP on Ubuntu 24 server. The connection fails only on the first attempt after each restart of the XRDP server, showing a server aborting error. Interestingly, this issue doesn't occur on Ubuntu 22, where everything works fine.
This issue occurs only on the first connection attempt after each restart of the XRDP server. If I try to connect again immediately after the first attempt, the connection succeeds without any errors.

Below are the relevant details from the .xorgxrdp.10.log file:
