Description
Hello!
My Codesandbox was working fine and suddenly this error started showing up when loading the code on browser: The sandbox stopped unexpectedly / A sandbox error occurred, you can refresh the page to restart the container.
Please take a look at the screen shot.
I don't know what to do, can someone please help me?
Thanks
