This is already addressed in the Compatibility List and has also been discussed in the GenP Stoat channels. Beta versions are not officially supported beyond simply being installable.
If you encounter problems with the latest Beta release, make sure that both the CC app and the individual Beta apps are correctly installed, updated and patched.
If the problem persists, your options are to roll back to an earlier Beta release or use the stable General Release instead.
Additionally, as noted in the Compatibility List, Beta versions are experimental builds designed for testing and feedback.
Adobe may change or break functionality at any time, sometimes even through silent or forced updates, which makes Beta software inherently unstable.
Because of this, GenP does not provide support for Beta apps, and any issues arising from Beta builds fall outside their scope.
If you choose to work with Beta versions, please be aware that you do so at your own discretion.
Should a genuine compatibility issue ever arise, it would only be addressed in a future general release, never through a standalone fix developed specifically for a Beta build.
