My distro is Arch Linux and the origin KDE plasma edition is 5.25.0-1. When the crash happened, the top panel was limpid and did not react to the click. While I used the command "top -d 2" to check the process information, I found that the process "plasmashell" took 100% of the CPU, sometimes even higher. Then I kill it with the command "kill 9 $PID" and rebooted the computer. Yet it was still not working after being rebooted, showing the same situation as mentioned. 

After searching on google, I try the way of restarting the plasmashell as the following process: type the command "killall plasmashell" the type "plasmashell &". But it still didn't work. By the way, when the plasmashell was loading, the terminal outputted the information as follows:

What is worth to be mentioned is that anything else about GUI with using plasmashell is fine and can be used normally.  

I thought it might a bug in the new edition of kde plasma 5.25.0, so I downgraded the KDE plasma to the last version before 5.25.0, which is 5.24.90-1, and rebooted the computer. Unfortunately, it still cannot save it from the same crashing. So how can I dill with it?
