Welcome to TF, I have two suggestions for you:
1- If you want to keep KB5001330 installed, you can run the different DISM command-lines and see if you still have the same issues after that. If so, go for a
repair install aka In-place upgrade. Here are the commands:
Dism.exe /online /Cleanup-Image /checkhealth
Dism.exe /online /Cleanup-Image /scanhealth
Dism.exe /online /Cleanup-Image /Restorehealth
sfc /scannow
Worth noting that with the Repair install, you won't loose your data files, neither your installed Apps.
Also, make sure the Microsoft Management console is well located in System32 by launching Task Manager > Details tab > look for mmc.exe and right-click on it to left-click File location. If it is not in System32 folder, it could be a virus (just a side note).
2-You can live without KB5001330 until Patch Tuesday on May 12, 2021 and see if you are back to normal after applying it.
BTW, It is very convenient to have a system image backup before doing anything major to your machine just in case something goes awry. Another thing, your System Spec in your profile is basically empty. A little bit of more info is needed.
Really hope that helps.
Cheers!
