Description of the problem

Sandboxes using @carbon/react error out or do not get past "transpiling modules".

How has this issue affected you? What are you trying to accomplish?

We ask that all bug reports submitted to Carbon have a codesandbox reproduction of the issue. We additionally use codesandbox a ton for examples and help/support. It's put a strain on our team trying to field support requests recently.

To Reproduce

We've had a hard time nailing down why this is happening. Unclear what from our package might be causing it. The sandboxes simply do not finish transpiling:

https://codesandbox.io/s/flamboyant-phoebe-oezq0f?file=/index.js

Additionally the example/template hosted in our repo gives an error:

Could not fetch dependencies, please try again in a couple seconds: Cannot read properties of null (reading 'match')

https://codesandbox.io/s/github/carbon-design-system/carbon/tree/main/examples/codesandbox

It might be related to https://github.com/codesandbox/codesandbox-client/issues/6443#issuecomment-1115103020 or https://github.com/codesandbox/codesandbox-client/issues/6607#issuecomment-1098993096, but am unsure.

Your Environment

Start with the linked CodeSandbox reproduction and the examples/codesandbox template, especially index.js, and trace where dependency fetching or module transpiling stops. Compare the @carbon/react sandbox behavior with the reported null.match error and the related client issues. Done means both the reproduction and repository example load successfully without hanging or dependency-fetch errors.
