Problem hosting certain plugins on iOS17


we are encountering some problems with hosting certain AUv3 plugins on iOS17.

Some of them (for example: Bleass Alpha, FabFilter Timeless)
crash when opening their UI. Others (Buttersynth for instance) don’t crash but their user interface is frozen and can’t be interacted with.

The issue is easily reproducible in the AudioPluginHost. All other hosts don’t have this problem.
