Explorer.exe high CPU usage after latest update, Win11

I am running Windows 11 Pro 64 bit version 21H2, build 22000.527.

After the latest update explorer.exe started to grab occasionally about 20% to 50% CPU power. Upon this high CPU time taskbar does not work, applications already on the desktop work though.

I have checked the desktop folder for any files missing the icon and I have also disabled OneDrive, did not help.

This problem is on almost all the time. It easies down occasionally but starts again. If I have the computer locked and log in again the problem starts immediately.

I do have some applications in desktop right button menu but they were there before the update without any problem(7-zip, WinZIP, NitroPDF etc).

This is quite annoying and prevents me working with the PC. The computer is Lenovo Thinkbook with 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz 2.80 GHz and 16 GB RAM.

Should I try to uninstall the latest update and is there a change that it messes up the operating system?
