Alamofire 5.2.2 TestFlight watchOS build crashes on Apple Watch Series 3 devices (32-bit) (Bitcode related?)

Question

Alamofire 5.2.2 TestFlight watchOS build crashes on Apple Watch Series 3 devices (32-bit) (Bitcode related?)

I have a WatchOS Application on TestFlight that is crashing on startup on Apple Watch Series 3 devices (32-bit). It works flawlessly on Simulators (Xcode 11.7) and Apple Watch Series 4.

I am using Alamofire 5.2.2 with Swift Package Manager. Latest Xcode (version 11.7). The device is Apple Watch Series 3 devices (32-bit) running latest final watchOS (version 6.2.8). Can you help me or give some direction on what is happening here?

I am calling a REST service that returns a JSON error file (response) and HTTP status code 401 (Unauthorized) if no gateway access token is given.

As I said this works in simulator and Apple Watch Series 4 device. I suspect of Bitcode, as in the past versions I had an iOS companion app and disabled bitcode generation, but now we only have the watch app and I cannot disable Bitcode generation.

The crash is somewhat like this:
