I was trying to uninstall and reinstall sql server but I ran into a number of problems.

The first of which is after I deleted the files and components for sql server 2019 I ran into this several times during reinstallation. Of course I did try rebooting but this results in the error prompting up again. I believe the main problem is the left over services/files no matter what I try I can't delete.

When I try to get the remove prompt from sql server 2019 it instead shows me this which I believe is a result of the failed installation since it couldn't correctly download so I don't have that as an option.

As you can see I can't remove setup either because of the files that are dependent on it. Unfortunately to delete the existing databases and probably the other files I need the remove prompt that you would normally get from choosing remove in the sql server 2019 uninstall but since as I listed previously I don't have access to that so I have no way to delete these services or files.

I'm honestly at a loss for what to do because I can neither uninstall the previous files or reinstall them because of the errors so I am stuck. I have tried alot of solutions by googling but to no avail, if anyone has any idea what to do help is greatly appreciated.
