Mac App Store stuck on get, install, get, install loop; can't sign into the App Store either.
I've recently got my MacBook Air (M1, 2020) up and running again after a while. Everything seems to work, except the App Store. Every time I try to install an app, I press "Get", then "Install", which only seems to loop again and again, and again. I've tried to sign into the App Store, yet it does not allow me to do so. If it explains anything, I have Screen Time on by my parent and cannot make any changes to my Apple ID as of now.
(Like, where is the sign in button???)
MacBook Air 13″, macOS 14.2
