Since 19.3.0, I have not been able to use the "check for updates" option,, and am presented with a "log" which I am not able to copy,, but can screenshot a partial .. Not a big deal as I can just download the latest version,,, but thought you would like to know ...

I doubt that this is a "Bug" It is more likely related to the likes of your AV or Firewall blocking the connection. When you check for updates a simple http request is sent to the server and if blocked then it will fail. Please ensure that the software has permissions to access the Internet you can do this by adding the software to your AV or Firewall list of exceptions.

I also think this is related to your firewall or virusscanner.
Make sure webbuilder.exe is added to the exception list.
