Sync to Serato Failed : Permission denied

I have all my music in an external hard drive, and when i try to sync to serato it fails right at the end.
there seems to be a similar issue i found on another post but the post is closed and the resolution doesn’t really point out how i can apply to my issue.
please help…

Try a computer restart first, that can help.

Otherwise, it is a permission problem where Lexicon is not allowed to write to that drive or that Serato folder.

i have went into settings and give full disk access to lexicon dj in security & privacy, also tried a restart with no luck. any other way?

Maybe you have a virus scanner or some other security software? Sometimes they block Lexicon.
Otherwise I don’t really know… Must be a permission setting on the external drive
