Fortnite Crash after using matchmaking portal on my creative map

Hello!

I created 1v1 map with matchmaking portal. Its already listed and public but when someone will use that matchmaking portal almost everything will disappear (Photo 1) for few seconds and he will be ported to new match. This is not that big issue because after port is everything OK but sometimes will game crash (approx 15% chance for crash)
5 people tried and it was same
