cannot start SQL Server 2019 after windows update but now works after go back to previous version of windows 10

I've been working with SQL Server 2019 for months now on a stand-alone machine. After I updated Windows 10 on 11/15/20, I can no longer start the service, though I can still start my 2017 version of SQL Server just fine (through SSMS or configuration manager).

Meanwhile, even though uninstalling the most recent Windows 10 updates didn't help me, using Recovery to go back to the previous version of Windows 10 did make it possible to start the SQL server service.

So my question has now become how do I proceed going forward? I can pause window updates for 35 days, but at some point, it seems that I am forced to update. How do I prevent the interruption of my SQL Server service?

Also would still love to know how to deal with Service master key errors as outline below.

Not clear to me how to deal with the Service Master key errors like this:

2020-11-30 16:20:48.65 spid9s      Service Master Key could not be decrypted using one of its encryptions. See sys.key_encryptions for details.
2020-11-30 16:20:48.65 spid9s      An error occurred during Service Master Key initialization. SQLErrorCode=33095, State=1, LastOsError=2.

Since I cannot use T-SQL to alter it since I can even get into the program, is there some other way to modify it? Do the subsequent errors all follow from this failure?

If I uninstall and reinstall the 2019 version, will I be able to attach the databases that are already attached to this instance of 2019? Or would I only be able to restore them from the latest backups?

Here's the error log file:
