Cannot install the new version on iMac

I’m not able to install the last release on to my iMac running MacOs Sequoia 15.6.1. When I try to move the app to the Application folder I get an error message that says: The operation couldn’t be completed because some items had to be skipped. For each item, select File > Get Info, make sure Locked is unchecked, then review the “Sharing & Permissions” section. Try again when you’re sure the items aren’t protected and aren’t marked “Read Only” or “No Access.”

Same reported in German here:
