Remote Desktop (xrdp) does not work on Ubuntu 22.04 using GNOME desktop

OS: Ubuntu 22.04.5 LTS. desktop is GNOME 42.9.

I installed xrdp using sudo apt install xrdp command. Firewall is not turned on because sudo ufw status command returns Status: inactive. xrdp is added into ssl-cert group using sudo adduser xrdp ssl-cert command, and XRDP service is restarted. Connection to the Ubuntu server has no problem. I can't upgrade to 24.04 and reboot.

When I tried to connect to the Remote Desktop on Windows using Xorg session type, I got an empty screen, nothing but all cyan or black color.

Below is the /var/log/xrdp-sesman.log file:

I have searched Internet for quite a while but got no solution for me. How to fix this? Thanks.
