Minecraft Education on Chromebook Code Builder Python Notebook "Network Error" when trying to load

Good morning!

A class is trying to play the Code Builder Python Notebook Lessons. When they load the world, or lesson, and press the 'c' key to bring up the code builder prompt, the "lesson" will load and be viewable for a split second, and then go blank with an error box popping up saying "Unable to connect to network, check your network settings."

We have our Chromebooks managed, but I am logged in on a Google account that has no restrictions. We have set a specific Chromebook while figuring out this issue to have no firewall rules, giving it full access to the internet, and I also took the Chromebook home and connected to my home network with the same error. 

We are using Dell Chromebook 3120 computers with ChromeOS fully up to date (version 134.0.6998.198) and running Minecraft Education v1.21.06

I have tried everything I can think of to get this to work for the students. OneDrive is enabled, I gave them access to 365 in case they needed something from Azure to load. Still the same error every time for every student. 

If any one can point me in the right direction that would be great! Thank you for your time!
