Why can I not update my world

So when I go to building and publish for windows or android it goes to the upload page fine but when I am on that page I can not click anything on it

There is scrips errors somewhere.

Check for errors first, but as another suggestion, take a closer look at the upload screen, if it’s all crunched up the buttons might not work. On the game window there are options for the aspect ratio, I usually go for 16:10 or there is one for free aspect ratio and then I can resize the view if things are looking crunched. It’s when the view looks portrait that screen isn’t really happy.
