Thank you!

I just recently experienced this same effect in a live release. The runtime error appeared to have occurred while 4 players were using the “Wasteland Rock” emote and .Teleport(Agent) was called.

I found a solution.

Instead of using the teleporter function in Verse, I was able to avoid the error by starting the trigger in Verse and then starting the teleporter teleport in the event system!
