How to reproduce:
1. Create an Xcode VisionOS Simulator Project
2. Install “PlayToDeviceHostUnity6” onto the VisionOS Simulator
3. Open the attached “IN-141679.zip” Project
4. Establish connection for Play To Device (Window → PolySpatial → Play To Device)
5. Enter Play Mode
6. Observe Console Window

Actual result: Error “[NetConnection] Unity editor version mismatch for host 9876: 6000.3.0f1 (d1870ce95baf) vs. 6000.3.15f1 (c1aa84e375f6). Serialized data may be corrupted!” is thrown.
Expected result: No errors and Play To Device is playing in the Simulator

Reproducible with: 3.1.5 (6000.3.15f1, 6000.4.6f1 ,6000.5.0b7, 6000.6.0a4)
Not reproducible with: 2.4.3 (6000.0.74f1)

Testing Environment: macOS 26.4.1, VisionOS Simulator 26.4.1

Notes:
- Impossible to check for Regression between PolySpatial versions as the project breaks when trying to downgrade to a version that would support versions between 2.4.3 - 3.1.5
- Additional error appears starting from 6.4:
“[Diagnostics] Exception in multicast command handler CommandHandlerChain, removing receiver: System.ArgumentOutOfRangeException: You must decide where to handle this command!
Parameter name: cmd
Actual value was RemoteEditorInputCommand.”
