Installed DaVinci Resolve (20.1) and it won't open when I ran it

I did, it work, but... it just open up another same app.

I can't see anything in that video. It's all blurry when I blow it up. Can someone please help me work this out? Installed Zorin last week. Followed directions to install Resolve and watched some videos to "fix" the install that obviously didn't work. I got it to where it all says it installed correctly but when I click on it I get a spinning wheel then nothing. Any help would be appreciated. Thx.
