What is the current behavior?

• On trying to analyse a component State using React Developer Tools, the analyse pane stays in the Loading ... state and throws this error

Uncaught TypeError: Cannot read property 'name' of undefined
    at O (backend.js:1)
    at s (backend.js:1)
    at s (backend.js:1)
    at s (backend.js:1)

    at t.<anonymous> (backend.js:6)
    at t.r.emit (backend.js:6)
    at backend.js:32
    at t (backend.js:8)

What is the expected behavior?

• Able to analyse component State as in the previous React Dev Tools versions.

Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?

• React Developer Tools version: 4.3.0 (12/20/2019)
• React Version: ^16.4.0
• Browsers:
  • Chrome: Version 79.0.3945.88 (Official Build) (64-bit)
  • Brave: Version 1.1.23 Chromium: 79.0.3945.88 (Official Build) (64-bit)

This looks like a duplicate of #17754 which was fixed by #17757 yesterday (but has not yet been released). If you'd like to provide a repro case for the bug, I can verify that it is indeed the same bug- but I'm pretty confident based on your description here.

The release should go out in the next couple of days.
