Crash Dump on Windows server 2019

We had on 06/21/2021 at 1:09 p.m. a crash of our tse server "windows-server-desktops-5". all connected users were disconnected from their session and it was impossible to reconnect in RDP. A restart of the machine solved the problem.
the system generated an 18GB dump that I analyzed with the windbg tool. this tool directs us to an error on a DLL (RDPUDD.dll) linked to a video driver on the machine. Have you ever encountered this problem and what is the solution to fix it?
Thank you for your help.
