Weird tree got into game

I joined in Studio Lite to keep working in my game, but then I saw this weird looking tree in it, I tried to delete it cuz idk it was just ugly but it didn't let me delete it, it even crashed the game. Did anything like this happen to yall?

Pls send help ;-;

UPD: I went to check if it also was showing in the actual game and yeah, it's there but I noticed something; when you go enough near you can hear smth that sounds like a heartbeat, it's so weird guys
