Sounds like Ubuntu underneath your Plasma. I’ve had the exact same experience when using Neon, Kubuntu, and Ubuntu+KDE. I install any non-Ubuntu based distro with KDE (like openSUSE) and whiz bang everything is working again.
The last time I tried it it crashed just from moving the panel around on the desktop. After a reboot it didn’t do it again. Plasma just does odd things like that sometimes.
And if you used Plasma 4 all the way up to around Plasma 5.15/5.16, Plasma was practically unusable due to instability. It’s why Plasma stopped being the default DE of choice and Gnome took over.
Plasma has improved a lot over the past year or two in particular, but it’s not close to as stable as, say, Gnome or Cinnamon.
How so?

I’ve experienced desktop crashing on Plasma, never happened on other DEs.
