try set env installed to false, run artisan compile command, then set it back to true.

php artisan env:set INSTALLED=false && php artisan streams:compile && php artisan env:set INSTALLED=true

I've done that and now I get this. What is this? C:\xampp\htdocs\pyrocms\vendor\laravel\framework\src\Illuminate\Routing\RouteCollection.php

    $others = $this->checkForAlternateVerbs($request);

    if (count($others) > 0) {
        return $this->getRouteForMethods($request, $others);
