When I want to open an app which I’ve downloaded outside of app store a pop up with the message of You dont have permission to open this app shows up.

My laptop is macbook pro 2020 m1 big sur version 11.1

I’ve checked of my user is the administrator or not and I found that I’m the only admin account on this laptop :

I’ve also tried to open app with rosetta but didn’t work either and also tried to make all users able to read and write in the permissions of the app info .

I hope anyone could help me open such apps . Thanks in advance .
