I have a Motorola moto g stylus 2025. I have not altered the OS or installed a custom rom. I simply have not signed into Google yet. I use aurora store to download and install app updates from the play store. What I'm curious about is why some apps won't even open at all without a Google log in? Is there something in your app that requires a Google account?
This is unusual. It does have libraries from MLKit for selfie segmentation. So, maybe missing access to Play Services.
I have play services. All the bits and pieces are there. This is a Google play services phone. I am just not logged in to Google.
