When I click on the preview button, it opens the page in the browser but the screen turns black and nothing comes out. It does not charge anything I have done. What can I do to see my videogame?

hello but the scene is complete ?? do you find any mistakes? what kind of platform do you use?

Maybe a hard refresh of the preview tab can help (Ctrl + F5 in your browser) ?, or open the console to check any error (Shift+Ctrl+i) :confused:
