We're crashing here:

Can you comment on the network state your system was in when you experienced this problem, as well as how you've configured networking on your machine? Anything unusual? For example are you not using NetworkManager or have you disabled or masked any of its system units? Etc.

For example are you not using NetworkManager or have you > disabled or masked any of its system units? Etc. I am using NetworkManager with no particular configuration. I mainly had this problem when connected via WiFi and when having no access to the internet. It happened one time after I killed my session with magic SysRq (AltGr+PrnScr+R then E then I) which also killed NM and logging right after. It also happens when I connect to public Wifi with a captive portal before I log in and thus have no internet connection Fixed today by Harald Sitter with https://invent.kde.org/plasma/discover/-/commit/f2bb47ae10d44cfae0a319ebe3293e3ff1bf9e2e! |
