Macbook air M1 doesn't have startup options
I've recently bought a used Macbook air M1 and used it for a while. Then I saw a software updaten notification, I wanted to install it but I couldn't. I also get some pop ups from safari and the App store is called "App Store". I tried to get in recovery mode and to format my ssd but I get this in my screen (see picture). I can still reboot but don't have any startup options. Any suggestions?
MacBook Air (2020 or later)
