There indeed seem to be a problem between the behavior shield and the protection some online games are using.
avast is aware of it and I’m pretty sure they are already looking for a solution.
It would not surprise me if they already had contact with developers of those game protectors.
For now leave the behavior shield disabled if you want to play.
I do strongly recommend to enabled it when not playing as it provides protection against e.g. ransomware.
