This occurs about 5% of the time I wake from suspend. The monitors briefly power on, showing only a black screen, and then power off. The system is not hung, other than the displays being off. If I suspend & wake 1 or 2 more times the displays will usually eventually come back up.
Output from journalctl:

Other than the above there is no other output from journalctl when run with —user-unit plasma-kwin_wayland or kwin_wayland.
From dmesg:
