Help? "You do not have permission to open the application 'Logos'."

Hi.  My desktop Logos won't open on my iMac today.  It says, "You do not have permission to open the application 'Logos'."  

I have used it on this computer for several years.

Last night the power went out for a few hours. 

I have tried re-installing it twice now.  

I'm on macOS Big Sur 11.7.9

Any ideas would be greatly appreciated.
