When the monitor turns off due to inactivity, it fails to reactivate after mouse movement or keyboard input. Manually turning on the monitor using its power button results in a "no signal detected via HDMI" error. The only solution is to force a system shutdown by holding the power button and then restarting the computer. My graphics card is an AMD RX 6500 XT.

So I'm having this issue as well and have been for a while. Once the monitors power off due to inactivity, I cannot wake them. I'll work on getting some debug info from the guides.

Sorry we didn't get to this issue yet.

Please attach the output of drm_info when the monitor isn't receiving any signal. You can get the output (and shut down the computer more nicely) with ssh from another device (for example your phone).
