react: Bug: React devtools shows "Unable to find React on the page" Incorrectly
React version: 16.12.0 Devtools version: 4.6.0
Steps To Reproduce
Don’t know.
The current behavior
React devtools shows “Unable to find React on the page” in the inspector Components pane. The website is a plain CRA app and the devtools is able to detect that the website is using a development build of the react when I click on the devtools icon in the browser extensions bar. I’m able to see the Components when I use devtools on a website other than mine (like reactjs.org). My app is served using the default react-scripts start command.
I don’t know what exactly is causing the issue but I can share logs or whatever that help to pinpoint the issue as you request.

Fixed the issue

Maybe re-open this issue?
None of the above solved the issue for me. macOS 11.6 / firefox browser 94.0.1
Any idea what to try next?
Closing the affected tab and/or opening a new tab worked for me.
I have had the same issue during past two weeks. Restarting the browser fixed it.
