Roblox Studio crash when change a specific script

Hello, recently i have some problems related to crash since i started my game.
When i open the script (infected of crash), and i modify it.
My roblox studio crashes.

Footage:

PS: This script gonna not be the final code.
I have a plugin that convert it automaticly to text and stores in a string Value.

That is incredibly weird, try to get Roblox’s attention.

I don’t know what you can do here. The script editor acts really weird.

What beta features do you have enabled?

Also, I recommend writing it all in a text editor and then modifying Script.Source.
