Script @php artisan coaster:update-assets handling the post-update-cmd event returned with error code 1

After getting back to work today and starting up the project. It told me "access denied" when trying to access the admin panel.

And after doing composer install / update it tells me "Script @php artisan coaster:update-assets handling the post-update-cmd event returned with error code 1".

Nothing I tried works. I don't know what it is that went wrong.
