beta FCC React-Redux section errors halt progress

[SpenserDavis]

Specifically, in the react-redux section, upon running tests on the challenges after I've finished the code (which I know 100% is correct from visiting previous solves and other forum posts) I am presented with the following issues:

"Cannot read property 'rendered' of undefined" (note that this one appears in the console window below the code editor and not the chrome console). After google searching this issue, I tried adding one line of code: " import ReactDOM from 'react-dom'; " and got error: 'require is not defined'

Not sure if these miscellaneous errors are relevant:
going to the home page of beta.fcc.org I get two errors:

vendor-main-eb0b5913eb.js:27
Uncaught TypeError: Cannot read property 'version' of undefined
at vendor-main-eb0b5913eb.js:27
at vendor-main-eb0b5913eb.js:27
at vendor-main-eb0b5913eb.js:27

and

main.js:1
Uncaught ReferenceError: require is not defined
at main.js:1

Upon trying to load any challenge page (before running any tests) I get the following error:

Uncaught (in promise) TypeError: Request scheme 'chrome-extension' is unsupported
at sw.js:279
