I simply disabled the Avast shields till the next restart and had no problems updating 4 systems.

With many computers having the sames issues, it was important for me to share about it

For me it seems that Windows 2020-11 Cumulative Update has solved the problem.
I was able to update a VM installation that has failed before on both ways:
- Installing the 2020-11 updates on Windows 10 Version 2004 and updating to Windows 20H2 with installed Avast Free Antivirus
- Removing Avast and updating to Windows 20H2, then installing the 2020-11 Cumulative Update and reinistalling Avast afterwards

Though I wouldn't go any risk and  won't make the update without a reliable backup/restore path

This solution was perfect for me. I had to reinstall windows 2 times. After upgrading to windows version 20H2 I tried to install avast and it gave a fatal error and windows did not recover.
After seeing this comment I did the procedure of installing windows 20H2, installing "Windows 2020-11 Cumulative Update" and then avast. Worked perfectly. There should be a warning on the avast website or something regarding the need for this update.

Thanks for sharing this info.

I didn't even disable the shields and the Windows 10 20H2 update went without a hitch.

Now if Avast was working before Windows 10 20H2 update and there was no change in Avast I don't know how Avast can be responsible.  Or I would imaging there would be many, many more such topics in the forums.

I personally have never disabled Avast for any Windows Updates (including Feature Updates) and have not experienced any issues.

It may not cause a problem but it certainly effects the speed of the update (upgrade)

Me neither.

Update issues are related to updating from ( much ) older Windows versions, it seems.
