When spawning the FPV drone sometimes other players freeze for a fair amount of time. Its a game freeze, they are still able to use their overlays, etc just fine while frozen.
In desktop I have experienced no freezes, so it might be a VR thing. Sometimes it will just randomly stop freezing anyone when spawning and be perfectly fine. Going far away to spawn the drone seems to avoid the issue.
Here is a video of when multiple people were having the freezing issue based on who spawned the drone: https://www.youtube.com/watch?v=EyHfXmCduww
