I have installed v12 on windows machins and created a sample bot. But i am unable to see the emulator to run the bot. Emulator became in gray colour and unable to see any emulator options also.

Hey @bumpy-agent-21056 does the emulator return if you refresh the page?

It is not. But i changed the port from 4000 to 3000 with localhost and i have given write permission to the botpress folder . then it was working
