Made a Mess of My Install, Help!

Tried to install on my M1 Mac and then realized this is going to eat most of my drive. The install worked and was clean. Wasn’t sure how to change install location, so I tried to delete. And tried and tried. Wouldn’t work from installer, tried deleting from the drive, tried a different profile. It just remains stuck on a partial new download for 5.1.

Any help is appreciated.
