cant gain access to external drive on mac after Mac OS update

have a 2tb external SSD and after the update it has a red circle with a white dash and says "cant be opened because you dont have permission to see its contents?? there is no password and never has been a password on it. how to gain access this is very infuriating!? i just updated mac OS to the latest and then this happened. there is no lock or unlock icon when using "get info" on the drive. just says no access
