Frequently losing debugging access while on latest RN version

I’ve been using RN for about a year now and I love it.

In the last couple months however I am frequently losing access to the debugging tools. Debugger statements stop workin and console logs no longer work. Sometimes I’ll see older console logs but any new ones stop working.

Really annoying! The only way I know how to fix it is to quit the Simulator, run yarn start --reset-cache and recompile from scratch. I have to do this several times a day.

This is the error I start seeing in the console where yarn start is running. Once this happens a few times there’s no hope and I have to do the above steps

This is becoming a huge issue – wasting tons of time trying to work around it.

Almost everyday after about an hour or so of development I lose all access to the debugger.

Can this please be prioritized or have some input from the react native team? I never saw this before 0.61.5

Manually setting the cli-debugger-ui version in package.json solved it for me, as described here https://github.com/react-native-community/cli/issues/1081#issuecomment-614223917
