I have tried:
reinstalling the debugger
removing all other debugging tools from chrome
clearing app and yarn cache
toggle DevTools react
toggle DevTools redux

Does anyone know what are the files affected by the debugger so i can delete them manually and do a clean install ?

[pouriabagheri]

so I managed to fix it by clean installing the react native debugger

1. brew uninstall --cask react-native-debugger
2. rm -rf ~/Library/Application Support/React Native Debugger
3. brew install --cask react-native-debugger

I have a similar question the react devtools is blank and can't toggle, I resolve it by installing react-devtools:
yarn global add react-devtools@^4.22.0.

Has anyone fixed this issue? I have the same. Nothing of solutions does not work.

I did this but command 2 did not work for me so I manually deleted the folder and reinstalled and it worked.

I fixed this issue. However, I could not solve this by uninstalling and installing it again. Then I remembered we have cache files for every application. With that in mind, the steps I followed to fix (Mac OS):

1. Open Finder
2. In the top, select Go -> Go to Folder -> /Users/${yourUser}/Library/Caches/
3. Go to Application Support folder -> Then delete the entire folder called React Native Debugger
4. Open the application again; it should be working.

It works. Great ! 💯

Having the same problem, installing it with dpkg. Removing and reinstalling does not work. I tried installing react-devtools:
yarn global add react-devtools@^4.22.0

I did not find the "React Native Debugger" folder under this path "/Users/${yourUser}/Library/Caches/Application Support/", but managed to solve this problem by turning off "Cache Storage" in the "Application" tab of the debugger.
The react-native-debugger version that I used is 0.14.0.

Don't know if this will help anyone but when my redux tools disappeared and I couldn't find the debugger preferences in the aforementioned path /Users/<user>/Library/Caches/Application Support/React Native Debugger, I eventually found the folder in question at /Users/Library/ApplicationSupport/React Native Debugger.

Removing it and restarting the debugger brought redux tools back.

I can't find the caches in both
/Users//Library/Caches/Application Support/React Native Debugger
and
/Users/Library/ApplicationSupport/React Native Debugger
Either toggling the cache storage switch in in the image above.
Also reinstalling is not working.

[powext]

It worked removing /Users/{user}/Library/Application\ Support/React\ Native\ Debugger

[palTarun]

npm i react-devtools@^4.22.0

Worked for me
