February 2022, Blue screens and loading loops when accessing the Scratch for CS First editor.
Users are reporting loading issues and blue screens when attempting to load projects in the Scratch for CS First editor.
We are aware of the issue and working on getting it resolved as soon as possible. In the meantime we suggest having the user refresh and/or restart their browser. If that does not resolve the issue, have them wait a few moments (3-5 minutes) and then try reloading again. We also suggest using Chrome as your browser to reduce the likelihood that you run into the blue screen.
