SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***

Powerdevil  crashes every time after upgrading to 5.27.2 when resuming from Screen Energy Saving mode.
**KDE is running in Wayland mode.**

STEPS TO REPRODUCE
1. Let the device idle to enter Screen Energy Saving. My device is connected to an LG C2 OLED TV monitor through HDMI. After the monitor said the signal lost. Turn off the monitor
2. Wait for 10 mins
3. Turn on the monitor and move the mice or click the keyboard.
4. Enter the OS and you can find powerdevil keeps crashing and there are tons of logs every second during the idle time.

OBSERVED RESULT
powerdevil crashed and "qt.qpa.wayland: Creating a fake screen in order for Qt not to crash" many times and all running apps like fcitx5, telegram, etc tray icon are missing. Though they are still running.
EXPECTED RESULT
Log in back normally
