SUMMARY I got into the unfortunate situation of my disk getting filled. The Plasma desktop became unresponsive, so I had to simply forcefully shutdown my PC. When I tried to boot again, I managed to reach the login screen, but upon logging in, I was simply met with a black screen with just the cursor visible. If Plasma is unable to boot without using disk space, perhaps it would be wise to reserve some disk, for instance by putting a large-ish file somewhere that can be deleted if disk space was to run out (with appropriate warnings to the user that they really should clean up some space very soon). But in general, it is unacceptable for the desktop to be unresponsive when running out of disk space. This effectively broke my computer and I had to boot into recovery mode and everything to get it working again. STEPS TO REPRODUCE 1. Fill your disk so you have no disk space left. 2. Restart. 3. The desktop does not start. OBSERVED RESULT A black screen with only the cursor visible. EXPECTED RESULT Normal boot.

Thank you for your bug report! Debian advises users to not submit bugs upstream (https://www.debian.org/Bugs/Reporting), as this version of the KDE software is out of support from KDE, and so it's possible that the bug exists only in Debian at this point. Could you report the bug to Debian using the report bug utility (https://packages.debian.org/stable/utils/reportbug)? If necessary, the maintainer of the package will forward the bug upstream. Thanks for understanding!
