Scrivener froze with his squares

Bonjour,
I’m Francophone, I’m new to this forum. I use an iPhone under ios 13 for two hours. Panic. Scrivener has become out of use. It presents a scroll of squares with the titles of the projects and nothing more. Would anyone have an idea to shed light on this divine problem?

Sorry, I should have read all the headings patiently. I answer myself to myself. The solution is mentioned under heading Scrivener 1.2 & ios 13 iphone iphone open projects. So thank you to the old ones.
