Dev Environment Not Working

I can’t run in local I’m getting error like (ECONNRESET) in terminal and the browser console log throws lots of error
but it was working b4 a week I don’t know what happened in jitsi

because some config has changed. Example configuration buttons are moved from interface_config to config

localhost loading after few seconds it came to welcome page

Please stop the process of going back to the welcome page (use the button to stop the loading of the browser) and see the error message on the console log Failed to load resource: net::ERR_FAILED
I got 44 errors including the above one

I think there is a conflict in the new code on the alpha and the old code you cloned. You can clone the latest code to be sure
