Start Menu no longer working 20H2

Well, since you're unable to do a repair install without losing everything, it may be best to create and use a new account instead for now.

Regarding the repair install problem, there was a fix posted for that, and MS released an upgrade to resolve that problem. That you can't run it is most likely to be because of a 20H2 bug. See e.g.
Repair Install Windows 10 with an In-place Upgrade

That said, your problem appears to be with one particular user profile. Given that, it is very unlikely an in-place upgrade repair install would fix it.

Looks like I'm unable to do an in place upgrade repair install. I downloaded the media creation tool from Microsoft and created a USB but it only gives me the option to remove everything.
My windows is Installed in the default directory.

The media creation tool is named MediaCreationTool20H2 and my current windows version is 20H2 build 19042.630

Run the .reg file first, then in-place-upgrade work with those options ungreyed: Repair Install Windows 10 with an In-place Upgrade

Yes you have to be up to Build # 19042.661 to do a repair install.

So I created a new account with a working start menu, but I absolutely dreaded the thought of setting up the new profile and getting all my apps/programs running and configured (it probably would have taken me a few days of stressful work). So in the end I took a wild stab and uninstalled the 20H2 update from programs and features...and guess what? I now have my stat menu back!

I think I will put off installing that update for a while...I'm guessing there will be fixes and patches added to any future updates. I really should have known better and left the update well alone, I usually run my machine a few months behind any big feature updates just in case there are any bugs.

Thank you to everyone who helped out and offered advice and possible solutions

Just FYI, I am not updating to 20H2 for a few months because I think it has too many issues based on my experience and other peoples post here and elsewhere.

I'm definitely going to hang back when new updates come out in future!

And do this frequently, especially before monthly updates, as we do here for free insurance: Backup and Restore with Macrium Reflect
