Error message "the media cache directory was not found or is not writeable"

I just updated to Premiere pro 2023 on my M1 Macbook Pro.

When I open Premiere I get the message box "the media cache directory was not found or is not writeable..." Then when I try to import files to a project i get the 'import error' "The requested file(s) could not be imported." Its a standard audio (Wav) file i've used in previous projects on premiere 2022 so I know it's fine.

I have deleted my cache and changed the cache location to different places in documents but I still get these errors.

I have also allowed Premiere 2023 permission to control my computer but this hasnt fixed the problem. Can you help? Otherwise I'm paying for a program I can't use. Thanks.
