Damaged and cant open message

Not a clue whats going on. Ive been using DaVinci for awhile and got this today:
\U201CDaVinci Resolve\U201D is damaged and can’t be opened. Delete \U201CDaVinci Resolve\U201D and download it again from the App Store.
This pops up right after the software crashes. I have deleted and redownloaded twice now. Any ideas???
Thanks!
