The cue ball has a very small chance to crash every user in the instance because of what seems to be a transform and floating point error.

This happened to me while I was playing both by myself and with others. All I did was hit the ball normally, then the ball disappeared, everyone froze and I crashed shortly after. I relaunched the game to see the instance that I was in was gone, which means everyone left.

I haven't been able to replicate this reliably, but I had a friend give me some logs. Here's an error that they got before their game crashed:
Infinity or NaN floating point numbers appear when calculating the transform matrix for a Collider. Scene hierarchy path "Architecture/ExtraGamesRoom/ExtraGamesDisableTree/POOL/VRCBCE (akalink) (new codebase) Variant/VRCBCE (Base)/Core Table Code/Cue Ball"
