I can not update or reinstall avast!

Hello everyone, everything good?

So recently an Avast update was released and it was where my problem started, I tried to update normally through the settings but did not update and gave the message “Unknown Error”, so I uninstalled the program and I tried to reinstall it is when the message "There was a error while completing the installation process “I have already downloaded the Setup Offline and other versions as” Pro "but I can not reinstall, if anyone can help me I will be grateful

NOTE: When you try to reinstall after the error message it displays the following “Installation Log”
