PHP Fatal error: Interface 'Symfony\Contracts\Translation\LocaleAwareInterface' not found in

I moved my project from a Linux computer to a MACOS computer and getting all sorts of errors.

I get these strange errors I can't figure out. I do also remember there being a warning that symlinks would not be copied onto my exfat formatted portable drive that I used to transport the code to my MAC.

So the folder I copied to my mac came from that exfat formatted drive.

I was originally getting this:

Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1

but then I did a COMPOSER UPDATE and it all went away.

Now I only get this error:

Any Ideas?
