Php Laravel, when running php artisan serve, I get an error

I'm working on a project in php/laravel. I've had no issues til, now. When I run the "php artisan serve" command I get the following error message:

In RouteCollection.php line 236:
syntax error, unexpected 'OPTIONS' (T_STRING)

I did not change anything here, I did not change the route file, either. I have tried switching branches and I get the same error message. I have tried running "Composer update" command and I get the following error message:

Loading composer repositories with package information Updating dependencies (including require-dev) require-dev) Nothing to install or update Writing lock file es Generating optimized autoload filcripts::postAutoloadDumpes -ansi

Illuminate\Foundation\ComposerSver --ansi handling the post-autoload-dumpcripts::postAutoloadDump @php artisan package:discover --ansi Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1load-dump event returned with error code 1

In RouteCollection.php line 236:

syntax error, unexpected 'OPTIONS' (T_STRING)

Any ideas? Quitting php/laravel is not an option either.
