TypeError: query.getObserversCount is not a function

Hello there,

I was recently migrating a project to react 18. I migrated everything successfully and there are no issues at all when I run the project. However when I go on the browser the app would not load and on the browser console I see the following error message:

It seems like the error has to do with the react query dev-tools as if I comment them out the project runs just fine with no issues at all.

React version: 18.1.0
react-query version: 3.39.1
