Hello, when the blank screen activates after 5 minutes of inactivity, my system becomes completely unresponsive.
Using Wayland.

Thanks for your help!

I believe I had a slightly different problem, but my system also sometimes froze during a blank screen (with Radeon 580). After I disabled power management on my RX580 audio device, my original problem went away and also system freezes seem to have disappeared. Worth giving it a shot. Use powertop, go to Tunables, and try toggling some of those options related to your GPU (in my case, it was Runtime PM for PCI Device Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere HDMI Audio [Radeon RX 470/480 / 570/580/590] set to Bad). It only persists until reboot, but it also prints a command, in case you want to run it on each system boot manually.

You should also file a bug probably against the amdgpu kernel driver, probably here:

Seems like someone already filed a bug report: RX 6600 XT fails to resume from suspend in 5.15.y series (#1819) · Issues · drm / amd
