Latest gatsby-plugin-netlify-cms seems to crash build

[wroughtec]

Description

When building/developing the ci crashes out with the following error:

node_modules/yoga-layout-prebuilt/yoga-layout/build/Release/nbind.js:53
        throw ex;
      ^
 Error: Callback was already called.
     at throwError (node_modules/neo-async/async.js:16:11)
     at node_modules/neo-async/async.js:2818:7
    at processTicksAndRejections (internal/process/task_queues.js:75:11)
 error Command failed with exit code 7.
 info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command

This did not happen with "gatsby-plugin-netlify-cms": "4.9.0" but occurs with "gatsby-plugin-netlify-cms": "4.10.0"

I have tried cleaning everything out (deleting node_modules and yarn lock and .cache) and tried many other things mentioned in previous ticket where this issue occurred on much older versions of the lib so potentially a regression has occurred or a conflict with another plugin perhaps

Reverting to 4.9.0 solves for now

Steps to reproduce

Run gatsby develop / build with "gatsby-plugin-netlify-cms": "4.10.0"

Expected result

Should not crash out of the build

Actual result

Crashes
