Per our understanding this issue only happens with transport stream (mpeg2ts) based HLS. cmaf based is not affected. (It also affected Safari15 in Monterey until Beta 7). In iOS15 Beta1/2 the issue is fixed, however there are still issues when mirroring over HDMI that require the "GPU process: Media" to be off...

The playback issue seems fixed in iOS15.1 beta1/2, except for a new issue related to HDMI mirroring... I don't know the security requirements of your service but maybe you have the option of temporarily downgrading to normal "http" key delivery instead of FairPlay?

My experience is the same. It reproduces when running Xcode in Rosetta mode. Sadly I have to run Xcode in Rosetta mode because of a slow 3rd party... (Hi Google).

The suggestion from Apple in the FB is to use audiovisualBackgroundPlaybackPolicy = .continuesIfPossible.

"Repeated Build & Run targeting iOS 16.1 and later simulator runtimes may sometimes result in a hung launch. (101990080)" Not sure where that 16.1 comes from. For us it happens on older versions than 16.1 too...

We have been informed through Japan developer relations that the issue was fixed in iOS18.3.2. Also the Update release notes mentions (sorry, this is from the Japanese release notes): 一部のストリーミング コンテンツを再生できなくなることがある問題に対応しています。 Translated: Addresses an issue that could prevent playback of some streaming content.

I believe I am seeing the same issue as you @asiergmorato . I have reported it as FB18656704

Just my layman guess. powersync-sqlite-core is a static xcframework. The contents of the framework is copied in to the app to /FitWoody-Watch.app/Frameworks/powersync-sqlite-core.framework/ But, my interpretation of the swift-build source, is that the framework must have a binary. So it creates a stub binary with name powersync-sqlite-core mobile.installd on iOS26 simulators seems to reject that file.
