Possibly AntiVirus blocked it on reputation basis, just guessing…
but yeah you can download it, scan with 2nd opinion AV (if you wanna be sure) and if good , go offline , turn off main AV, install app, turn back AV go back online.
Managed to find out what was happening and it was a Microsoft setting that I don’t know how it came about, their app store tried to take over any attempt if I tried to install the Shotcut program or any other program and I had to go to their App store so I called Microsoft and in 30 seconds it was fixed with no excuse. I lost over 8hrs trying to figure out what was going on.
Live and let live, now the hardest thing to learn is the voice over or narration.
