Failed to run on iOS 26 Devices using Xcode 26

This issue has been around for a while for me. Xcode 16.4 doesn't have this issue.

iOS 26.0 (23A5326a) & iOS 26.0 (23A5336a)
macOS 26.0 Beta (25A5351b)

>>> Fatal error: Attempted to read an unowned reference but the object was already deallocated <<<
CoreSimulator 1047 - Device: iPhone 16 Pro (E0320FA4-9096-402C-9972-1AA0FFE5CE72) - Runtime: iOS 26.0 (23A5326a) - DeviceType: iPhone 16 Pro

Start by reproducing the failure on the listed Xcode 26 beta, iOS 26 simulator, and macOS beta versions. Use the reported “Attempted to read an unowned reference” fatal error as the first investigation point; done means AltStore launches without this crash on the affected setup.
