How to uninstall Destiny 2?

I havent logged into my blizzard app in a very long time and I still have over 90gb of destiny 2 installed on my pc. I can locate the folder and load up the game but it wont let me past the first screen without an error coming up. I try to uninstall through my control panel and it gives me error blzbntbnu00000006 every time. The game isnt listed in blizzard app so I cant uninstall through there and all threads i have seen on the subject are closed without any solution being given.
