Using a Dell G5 5590.
Windows 11 (Although this error happened on 10 prior to accidentally upgrading).

Sometimes there can be a weak Ribbon connector in a laptop, and a light shake would obviously fix it.
But by the sounds of it, there seems to be a conflicting issue thats related to windows update.
What I would personally recommend is running Disk Cleanup, and clicking ok, then open it back up and click the clean up system files and click ok on that, and then repeat them steps a 3'rd time to get to more options to clean up the system restore and shadow copies.
This will clean up temporary files related to system updates, allowing them to load fresh the next time you attempt to do windows updates. and cleaning up the system restore/shadow copies, will delete any old backups that are not being used.
Once you complete these steps, then you would want to restart, then run a disk De-fragment.
Then turn the laptop off for about 3 minutes ( Preferably Take out the battery if not too much of a hassle ).
Then turn the laptop on, run windows update , download anything if possible. and then all problems should be fixed.
