KDE black screen after opening lid

fr flag

I get a black screen when I open my laptop lid, and I have to reboot the system by pressing boot button. The last time I was trying start plasma (in tty by pressing Ctrl+Alt+F3)

kstart5 plasmashell

and there was additional output information that may help.

kstart5 output:

kstart5_output

It says about Qt platform plugin 'xcb' that could not be loaded even it was found, and reinstalling the application may fix the problem.

My plasma version is 5.27.4.

Other system information:

The black screen does not appear every time I open the lid but about once a week.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
