Perhaps a leading backslash? else a "use \ReCaptcha\ReCaptcha" statement?

Tried all kind of combinations, none of them worked. Went to ReCaptcha.php and removed "use namespace ReCaptcha;" and then it worked, but now getting other classes not loading up. I tried other vendor librariers and they all fail to register the classes for some reason. Tried this one aswell and i get "Class 'Anhskohbo\NoCaptcha\NoCaptchaServiceProvider' not found" error.

are you sure you just didn't need to run

composer dump-autoload
