Android App Crashes on Startup, but not when i toggle Development Build.

So my game works 100% on desktop and was previously working on mobile.

After the last build the app would start I would get past the splash screen, and see the homescreen of my app for maybe 0.5seconds then the app would just close. No "App has stopped working" just goes striaght to my launcher.

However, when i toggle "Development Build", Autoconnect Profiler, and Script Debugging it works fine.

Any idea what might cause this?

Thanks!

Edit: I Used ADB and saw no errors. Also i used an older android phone and it worked perfectly...? Please help! I have also uninstalled and restart the phone. It worked on a S5 and dosnt work on my rooted Google Pixel.
