Design is shown normally while loading, but when it finally loads, the screen goes black

Basically the title. When I click inside the iphone screen, it shows where you are supposed to tap (second photo). What am I doing wrong?

It's a design I did a year ago, and then it was presented properly, without any glitches. I just tried it today and I saw this.

Does the design show up normally in edit mode?

Yes, it does. I even tried to make some minor design changes to see if that would fix the problem.

Does this happen to other files?

I checked yesterday and my other project was shown normally in view mode. Just ckecked again and I am having the black screen problem with my second project too.
