Yeah similar experience here, At work we are forced to use a distro with GNOME (well at least it is GNU/Linux and not that Microsoft bloated spyware) and yeah I have plenty of crashes in GNOME. No crashes at home with KDE Plasma on openSUSE Tumbleweed. It has been rock stable.
I've migrated to Mint and haven't tried KDE for the last 10 years, but I would have a hard time calling GNOME stable.
