php – Unknown: Failed opening required on line 0. laravel 5.6

I just installed laracast/flash and updated nesbot/carbon via composer. The cmd went nuts while downloading carbon. Cmd interface displayed scattered words and boxes all over the interface for a while and the download was completed.
Did php artisan serve at localhost:8000 and I’ve got the following errors.

Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0

Fatal error: Unknown: Failed opening required ‘C:xampphtdocsNC WorldProjectNameserver.php’ (include_path=’C:xamppphpPEAR’) in Unknown on line 0
