Problem

MacBook Air Early 2019 11"

Starting up computer with a flashing folder with the ? Sign on it. I've turned it off and turned on again but using CMD + R. Turns on again with a spinning globe saying"internet recovery this may take a while." Waiting for about 10 minutes before iit is a still globe with a caution sign. At the bottom it says apple.com/support -2100F.

Now when I restart MBA again it just restarts the internet recovery , sometimes it has a time at the bottom (now it says 2:34)

What can I do to fix it? It was perfectly fine before I turned it on. The only thing that could be related is an iOS update that I've post poned for a whild now. What do I do?!
