Logic File Share Problem

Hi

New problem. I've just upgraded my iMac to a Apple 4 chip version and installed logic etc.

When I File>Share>Mail I get the usual dialogue box to select and then when I hit OK I get an error message I've never had before in years of using Logic.

Logic has full disk access, I've checked all I can and I cannot make this go away.

Can anyone please help it's a real inconvenience!
