I'm not getting any errors.
Mouse clicking by speech isn't working in Avast. It's being blocked by Avast. So I can't do anything in Avast, because I don't use physical mouse at all.
I use Windows 10 64-bit and latest Avast Free Antivirus version (downloaded today from official Avast website).
Presumably it has worked previously with Avast installed ?
Does it work when used outside of the Avast user interface, e.g. with other applications, as you are saying "it is blocked by Avast" but you are also saying "I can't do anything in Avast"
Avast would generally throw up an error or alert screen "if it is blocking."
Whilst I don't use workbyspeach, I'm using win10, but I'm not using the latest 23.3 version, so I can't try it to see.
What version were you using when it last worked ?
If using Avast Free then FilePuma.com keeps old versions this should show 23.2.xxxx
https://www.filepuma.com/search/Avast/#gsc.tab=0&gsc.ie=UTF8&gsc.sort=&gsc.q=Avast - download and save this version to your computer.
If you are able to uninstall Avast from the Control Panel - Programs and Features - Avast - Uninstal - restart and install Avast Free 23.2.xxx
