SUMMARY Every time the monitor turn on again after light locker kicks in (turning off the monitors), plasmashell crash and all panels and widgets disappear. I can reproduce it on 2 different hardware PC, every time, since more than 2 years. STEPS TO REPRODUCE 1. wait until light locker kicks in, and monitors (dual) turn off 2. type some key to turn on again the monitors. 3. the monitors turn on 4. enter again to the session (unlock) 5. desktop crash OBSERVED RESULT plasmashell always crash when monitors wake up EXPECTED RESULT no crash SOFTWARE/OS VERSIONS Operating System: KDE neon 5.27 KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.104.0 Qt Version: 5.15.8 Kernel Version: 5.19.0-35-generic (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 5600G with Radeon Graphics Memory: 30.7 GiB of RAM Graphics Processor: RENOIR Manufacturer: Gigabyte Technology Co., Ltd.

What is "light locker?" You mean the lock screen? Looks like a calendar plugin is crashing: > #5 0x00007f5d557bae1e in ??

Huh, that's a very strange translation. The original English term is "Screen Locker", and I would expect the whole text to be translated into Spanish, rather than half of it translated into Spanish and the other half of it changes into a different set of English words. I'd encourage you to submit a bug report about this to https://bugs.kde.org/enter_bug.cgi?classification=Translations&component=es. Anyway, can you get debug symbols for the crash?
the desktop crash every day, when screensaver turn off both monitors, and I wake up the session. But cannot catch any error report like in previous crashes.. I'm forced to kill all plasma and restart it again every time to work again. I also tried to remove calendar, but the problem continues.
