You’re welcome.

Not sure if glitch in the code would see this inconsistent results, only effecting some rather than all on a certain avast build. Whilst there is always a possibility of server load in respect of beta builds as I don’t know if virus definitions are also isolated on to a small range of update servers in the same way as beta program updates are.

One thing for sure it is a mystery, thankfully you are back up and running.
