We can’t understand your issue without more details. It may help if you can post hardware details using inxi -Fzxx in a terminal (as pre-formatted text so it can be found with web searches). If you are using a Live USB environment you will have to install inxi (it will not be saved if you reboot). You can also use journalctl --directory ... in the Live USB terminal to view the journal records from your system disk. You will need to mount the root directory of the system disk. See man journalctl for details. The journal collects massive amounts of data so you will need to use “filter” options to select relevant details. See: journalctl Command in the Linux Handbook

I’ve found an issue with plasma crashing

I think fcitx5’s problem,because libfcitx5platforminputcontextplugin.so this file cause plasma crash.
