I also got this error. The code that I used to produce this error is here. (Accompanying HTML and CSS files are available too, just change the file name in your browser's address bar to index.html or main.css.)

Reinstalling the extension fixed the issue for me

Reopening chrome DevTools fixed it for me

One possible cause of this issue is when multiple react devtool instances are running on the same page. Restarting the devtools (by close and open chrome devtools, or re-install the extension) often helps. If this issue still persists please let me know! It would be very helpful if someone can provide a way to reproduce.
