Log of the error obtained in KSystemLog

SUMMARY
***
The taskbar randomly disappears and then automatically restarts several times throughout the day when you mouse over the taskbar icons
***

STEPS TO REPRODUCE
I can't say a safe way to reproduce the problem since as I say, it happens randomly sometimes, but the problem happens when you hover the mouse pointer over some icon on the taskbar

OBSERVED RESULT
The taskbar disappears and then reloads automatically

EXPECTED RESULT
The taskbar should not disappear when you hover the mouse pointer over one of its icons

ADDITIONAL INFORMATION
This error began to occur after updating to one of the versions published in the last two years, before this error did not occur.

I have tried from KDE 5.27.1 with a session in Wayland and with Linux Kernel 6.1.13 and 6.2, and in both cases the same thing happens. I haven't tested much with X11, but in this environment the time I've tested it seems to work fine, so the problem seems to only occur on Wayland.

I attach the log file obtained with KSystemLog. The error I believe occurs at line 964:
