[Bug] Yarn 2 install Failed with errors on react-scripts 4

[Kizmar]

• I'd be willing to implement a fix

Describe the bug
I don't know if this is a Yarn issue, or a react-scripts issue...

I just deleted our yarn.lock and node_modules folder so I could run a clean yarn install to debug an issue with CI. Long story short, I debugged this by removing all dependencies and slowly added them back in while running yarn install to see which one was causing the error below. Come to find out, it's react-scripts: 4.0.0 that's causing it.

The error in question:

YN0066: │ fsevents@patch:fsevents@npm%3A2.2.0#builtin<compat/fsevents>::version=2.2.0&hash=127e8e: Cannot apply hunk #1 (set enableInlineHunks for details)
...
YN0000: Failed with errors in 25s 499ms

To Reproduce
Run yarn add react-scripts --dev does it for me - or - run yarn install with react-scripts: 4.0.0 already in your package.json dependencies.

Environment if relevant (please complete the following information):

• OS: Windows 10
• Node version 12.19.0 & just installed Node 14.15.0 (same result)
• Yarn version 2.3.3 (yarnPath: .yarn/releases/yarn-berry.cjs)

Additional context

I also tried re-installing react-scripts on a global level and running yarn install again but got the same result.

fsevents released a new version 6 hours ago so seems we need to update the patch https://github.com/fsevents/fsevents/releases/tag/v2.2.0
