Win10 "User did not grant permission" error despite not being asked

I try to flash a file but immediately get a “User did not grant permission” error despite it not asking for permission in the first place. I’ve tried running as administrator and that didn’t work. I uninstalled the program and deleted all the stuff I could find related to it but it managed to remember the urls for isos and drives on my system I wanted to flash when I reinstalled somehow. I’ve tried portable and installer versions. Nothing is working for me.
