SUMMARY
I added several widgets by dragging them from Widgets Explorer and dropping them
on desktop. I closed the Widget Explorer, reopened it and then Plasma froze.
It became unresponsive and its colors desaturate.

Operating System: KDE neon Unstable Edition
KDE Plasma Version: 5.23.80
KDE Frameworks Version: 5.88.0
Qt Version: 5.15.3
Graphics Platform: Wayland

Continuing.
