What happens when you check "Repair to Continue"? This message is saying you don't have permission to the folders you want to import/export to. External drive? Is this a Mac? Recently upgrade to Catalina? Catalina is known to limit user permissions until you go in and give yourself read/write permissions to all folders you need to use.
You can go to the System Preferences of your Mac, then Security and Privacy, then select the Privacy tab. You can add Photoshop to the Accessibility list under the Privacy tab and grant permissions to Photoshop under Full disk access.
