Thank you very much for your response.
I followed your advice and ran SFC/Scannow - no corrupted files! What else can I do? If there’s anything else possible, should I temporarily remove my antivirus - Avast Premium?

1) You can run a SFC scan and repair

It should tell you that the protection has detected damaged items that need to be corrected after a restart. At that moment, restart.

Then, run a DISM Repair
Still in the command prompt window, run these two commands successively.

DISM /Online /Cleanup-image /Scanhealth
DISM /Online /Cleanup-image /Restorehealth

(be careful, there is a space before each command starting with / /Online /Cleanup-image etc)
Make sure that the scan and repair reach the end without any errors appearing.

Restart the computer.
Try to install the updates again, if it continues to crash, move on to the next step.
