You can use the events in the disable manager to disable your own player character - The example below is just a guide for the included player character
Disable Manager Setup
Click the "+" on either the OnPlayerDisabled() or OnPlayerEnabled() to add new events
I disable the FirstPersonController script by selecting the FirstPersonController > Bool Enabled
I disable the CodeDeviceInteractor when the player is disabled
I actually enable the CodeDeviceUIManager.ShowCrosshair
