I have been working on an app with Expo which works well on the simulator and via the Expo client however after starting testing on testflight the app will sometimes crash during startup the screen goes white for a moment before going black and then crashing.
Hi, that’s not an error I’m familiar with. Looks like it’s happening during the network request for some image resource while loading your app. It also looks like the stack trace originates in React Native’s code, rather than in Expo’s code. Here are some things I would try:
Try running your app in Expo Client with the dev flag disabled and minify enabled. This will be the same JS bundle you’ll get in a production build of your app.
If you aren’t making any progress, you might just try updating your Expo SDK version to the latest one, because it will include a newer version of React Native, and it’s possible they already identified and fixed this in their library.
