Macbook hangs occasionally while using Remote Desktop on the mirrored external monitor

I am using MacBook Air M1, 2020, 16/256, 7 cores of GPU. I also started to use external display as a mirror:

LG ULTRAFINE 27UP850N-W:
  Resolution:	5120 x 2880 (5K/UHD+ - Ultra High Definition Plus)
  UI Looks like:	2560 x 1440 @ 60.00Hz
  Main Display:	Yes
  Mirror:	On
  Mirror Status:	Master Mirror

When I use Microsoft Remote Desktop for Mac (Version 10.9.5 (2179)) notebook occasionally hangs then reboots. There were no such problem when I used the notebook without external monitor. Also it hangs only while I use MSRD and no problems while using any other app. Can I get support with my issue here or where should I post it? A can also provide crash reports.

Have you tried to set 2 monitors to the same resolution? You can pay more attention to the resolution , confirm the settings in your app(remote desktop) and system.

@Karlie Weng thanks for your reply. I am not sure how to set different resolutions for monitors in mirror mode. My system settings are 2560 x 1440 Settings in RDP are as on a screenshot below. I use RDP only in full screen. Targeted OS is Windows 10 Pro 22H2
