Unfortunately the backtrace is incomplete and missing debug symbols that we need to figure out exactly what's going wrong:

In addition, Plasma 5.21.5 is no longer a supported version, so there is a chance this crash has already been fixed. Please upgrade to 5.22 or preferably 5.23 or later.

Finally, it appears that you are using Kali Linux, which is not appropriate for general use, and you will find a million and a half other little weirdnesses like this, because running everything as root is explicitly unsupported and never recommended. I would encourage you to re-install your system with a more appropriate general purpose Linux distro, such as one of the ones you can see at https://kde.org/distributions.


Thanks for understanding!
