Starting the sample EchoBot bot produces error Sorry, something went wrong with connecting bot runtime.

The issue is producing in a nightly build version.
Steps to reproduce the behavior:
The bot should load and start running.

The root cause might be similar to the other issue I filed regarding bot runtime: https://github.com/microsoft/BotFramework-Composer/issues/3443. Although since both produce in different areas and when performing different actions, I logged it as separate issues, just in case they are unrelated after all.
I have the same issues and it happens when update the nightly update. It was fixed once I installed the main version again but not that does not help either. The following issue also occurs: #3443 .
I just fixed it by Uninstalling the composer from C:\Users\
@manashty Downgrading to the latest stable does indeed work around the problem temporary - as long as in settings you deactivate the nightly builds flag.
Hi @manashty this issue was fixed in https://github.com/microsoft/BotFramework-Composer/pull/3479
