Windows 10: Unable to update past windows version 1909, error "0xc1900204"

As the title says, my computer is refusing to update past version 1909 to version 20H2 or 22H2, I've tried already to use the windows 10 upgrader from: https://www.microsoft.com/en-us/software-download/windows10 however it wont let me keep my files, the options are all greyed out except just wiping the computer. I've tried other solutions from this post:https://answers.microsoft.com/en-us/windows/forum/all/20h2-error-0xc1900204/7ab5af11-81f2-4a25-974e-d0e254144caeI don't want to wipe my computer, what can I do?

Update Error - 0xc1900204 - Version 1909 - SSD Boot

Hello All,

I'm having problems with Windows Update version 1909, I am getting error code 0xc1900204.

I have performed all the steps as outlined in Redirecting but have had no success.

My current setup:

SSD - Bootdrive (C Drive)

HD - All other files (A Drive)

All content is saved to the A Drive: New Apps, New Documents, Music, Photos, etc.

I am thinking I my not have edited the registry editor option correctly. Per troubleshooting with the registry editor, I changed "ProgramFilesDir" values to C and it still didn't work. Below is a list of over values in the folder, should I redirect all
to C?

Update Windows 10 version 1909 to version 21H2

Can I Update Windows 10 version 1909 to version 21H2 (latest)?

Then Please send the useful steps to do that...

By changing windows version 1909 to 21H2 does it removes all files(music, videos, software,etc.) present in my laptop or it is safe, nothing will be deleted.

Now I am not getting critical updates for windows version 1909.

Please anybody give suggestion regarding this matter.
