Empty AEM form throwing error in console: "Handler of component is invalid -> TypeError: Cannot read properties of undefined (reading 'flow')"

[uniqvaibhav]

I have just setup AEM 6.5.7 in local with service package adobe-aemfd-linux-pkg-6.0.234 to setup some AEM forms but if I am creating any AEM form it throws error in console as shown below, please suggest any resolution for this problem. 

Logs of browser console:

Do you see any packages uninstalled state on the packageManager - http://localhost:4502/crx/packmgr/index.jsp 

You need to make sure that packages are installed or reinstall the forms add-on one more time and review the error logs for any issues.

Also, do you see any errors in the logs while creating the AF?

I have attached error logs in here, all the packages are installed, also I have tried to reinstall folders as well but still facing issues.
