- Linux: Fixed an issue where the Package Manager's prompt keeps reappearing to resolve packages
- macOS: Fixed loss of input and occasional crashes when connecting and reconnecting controllers.Z

- Physics: Clarified how certain HideFlags affected physics
- Physics: Fixed a crash when the maximum allowed ArticulationBody components (64) was reached in a single hierarchy
- Physics: Fixed an issue where the physics debug window was lost forever after entering the playmode
