Bug with Physics

So I either have a major glitch, or Horizon Worlds is totally screwed up?   Seems others also having same issue. The last 6 days I have been having this issue, the object will just fall through the other object.    I have created a world in VR and in Desktop, simply made the red object grabbale and with physics, and when it lands on table top, it just falls through to floor.    It’s never done this before but now does this.  Erase, do gain, same issue.   Can anyone help with this or know if this is a bug in system?
