Issue Description

I created a release workflow within fastlane for our Flutter app into Testflight on AppStoreConnect. It works well when the lane is ran locally on my machine and I'm able to install the resulting IPA on my phone from the Testflight app without any errors.

When I execute the same process on a github action, everything runs smoothly, but when installing from Testflight and opening the app, it appears to be frozen on the LaunchScreen.

Here's my github action
