Everytime I run new code, the whole screen freezes.
When I reload the page, it takes a very long time to load, and after a while, a notification appears and says: “The initial code to build the world never finished running. It’s probably either really slow or has an infinite loop. Or there might be a bug. You can either try running this code again or reset the code to the default state. If that doesn’t fix it, please let us know.”
What should I do??
