Microsoft RDP unable to connect after update (MAC VENTURA 13.3.1)

I had updated my Microsoft RDP via App store yesterday. Shortly after, I cannot access my server CPU. The error message is 

"Your session ended because of an error. If this keeps happening, contact your network administrator for assistance.

Error code: 0x4"

On my Mac, I had uninstalled the App, restarted the computer, restarted my internet, updated my Macbook version, but error still persists.

My iPhone connects to the server using the Microsoft RDP app successfully though. So I think it is a Mac issue.

Please assist if possible, thank you!
