On iPhone, dev client is crashing on refresh

Video: Dropbox - app_crashing_ios.mov - Simplify your life

Does anyone know what could be happening? When I shake the device, the menu comes up AND the app screen turns white and it starts “downloading” again. When it completes downloading the app just crashes.

Then when I reopen it, I can reload the app like normal.

Hey @tennisbum, could you try accessing the native logs? They tend to provide more detail and better insight into what causes a crash.

Cheers,
Adam

Ok, should I follow the instructions here: Viewing logs - Expo Documentation?

I have the same problem.
Here is the native log when the crash happens, filterer by the app’s bundleID
I tried removing the app components one by one, but nothing works.
