iOS 15 and app terminating on start. It does not even look like it is crashing

I just recompiled an app with Xcode 13.1 and deployed it on one of my iPhone running iOS 15.1.1 and when the app starts, it just gets terminated.

It happens both if I run it from Xcode or by tapping directly on the app's icon.

It looks like the app is not even running and crashing. I checked the console logs and all I can see is stuff like this:

    NSUnderlyingError = <NSError: 0x28762b840; domain: FBWorkspaceScene; code: 1; reason: "Client process exited.">;

}

I tried to wade through the logs that are not errors but I couldn't find anything relevant. Has anyone had this issue before?
