OK, I got there, I see the short list of about 8 updates and, as you mentioned KB5001330 is not there. But...You can uninstall an update by going to Settings>Update & security>Windows Update>Advanced option>View your update history>Uninstall update The update you wish to remove may not appear at first.
...SERIOUSLY? Just start removing random updates in order to "unlock" the problem update to be removed? What if some of those updates are beneficial? Why is the list not comprehensive from the start and you just scroll down to the desired update? Why can't I just search my C: drive for "KB5001330" to isolate and remove the problem without tampering with several to dozens of other updates that may be addressing other issues with my machine? And most importantly, why would you need to remove several potentially beneficial updates in order to access the problematic one?Continue to remove updates, top of list down, until you can uninstall the desired update..
So I started following your instructions and selected to uninstall the top update on the list, not knowing what that potentially might be fixing. It was taking over 5 minutes to uninstall, and I chickened out and cancelled it - many times my computer has encountered issues leading me to follow instructions that don't make any sense which ultimately ends in me needing to run a system restore overnight and lose all the data since the last time I created a safe load date, which I haven't done in quite some time. I checked the list of updates and there it was - KB5001330 right at the top of the list, but it had today's date and not 4/13/21. So I don't know what that file is but it isn't the problem I'm trying to fix but also clearly isn't anything beneficial so I tried uninstalling it and it failed to do so.
Apologies if you are taking your time to try to help, But this seems incredibly fishy...
