How to fix:Windows corrupt user profile(I suspect)

I am pretty sure I have corrupt local user on my main PC. There are programs that when I search for from start menu, and click on them, they don’t launch. If I scroll the start menu to find those programs and launch that way, they work. I also have couple of programs that refuse either to authenticate through their servers to let me log into them or launch all together.
Those issues are solved as soon as I log into another local user.

What I’ve tried:

• SFC/DISM
• Windows updates
• Driver updates
• Disk cleanup as well as cache
• Deleting everything, as well as registry entries to said programs that refuse to cooperate.
• Restarting explorer.exe for the start menu search anomaly

My question right now is more so, if anyone can confirm my suspicions as well as, what’s the easiest way to migrate all the data from one account to another. My main concern are any saved configurations in all the programs I’ve used for 6 years on this build and also anything in appdata/documents that those programs might’ve stored there.
I have written down everything I can think of backing up for past couple of months, and yet I’m still afraid I’ve missed something.
