As ray_cai outlined the issue was related to the LaunchImage. @howard_kang this fixed the issue for me. Remove LaunchImage from the Asset catalog. Remove references to LaunchImage from your build settings. Add Launch Screen storyboard to the project. Add parameter Launch screen interface file base name with the name of your storyboard Launch Screen.storyboard to your Info.plist file.

@DTS Engineer I utilized iOS 26.1, the issue @ray_cai outlined above was related to the LaunchImage. The fix is: Remove LaunchImage from the Asset catalog. Remove references to LaunchImage from your build settings. Add Launch Screen storyboard to the project. Add Launch screen interface file base name with the name of your storyboard Launch Screen.storyboard to your Info.plist file. I am not sure why this was causing a hang with the tab bar, maybe the Launch Image is not compatible with iOS 26.1 & iPhone Air, this issue was not occurring on other versions of iPhones.

Albert, I have also filed a bug report FB21320686 I have attached a trace and a project file to reproduce the issue. ray_cai, what has your fix been? Does removing the legacy launch image fix the issue?

Albert, I have downloaded Xcode 26.2 (17C48), the issue exists and is isolated to the iPhone Air. Both iPhone Air 26.2 and 26.1 simulators have this issue. Other simulators on Xcode 26.2 remain free of this issue. Let me know if there is additional information I can provide.

I am running into the same issue, have not found a solution yet. It seems to happen during the Liquid Glass animation transition. I'm not able to disable the new Liquid Glass UI using this flag UIDesignRequiresCompatibility are you?
