Horizon wont open on my computer

So i have a windows 10 dell laptop and im trying to mod a borderlands 2 save but I download horizon and try to open it and it does the little loading circle but then nothing happens, ive tried everything like running as administrator, disabling my antivirus, uninstalling and reinstalling, restarting my computer, ive done it before a long time ago idk why it wont work now

Go to properties on Horizon and try using it with compatibility mode see if that works. if not verify that you have the latest Horizon download
