Why am I getting this "AppLifecycleEvent" crash? macOS has been greeting me with weird crashes caused by scripts from &quot;~Library/Application Scripts&quot;:

The first line in the stack trace leads to this:

6H4HRTU5E3.com.avast.passwords.PasswordsHelperApp

I discovered that this is a &quot;script&quot; from the &quot;~/Library/Application Scripts&quot; folder. However, it looks like this is a ghost folder - there are only subfolders in there with no files whatsoever:

What is this folder and is it safe to erase it completely if it's empty anyways?
The cause of your crashes is Avast AV software. Make sure you've installed a version that is compatible with your OS, or uninstall it completely (this may require running an uninstaller - contact Avast for details).
Application Scripts are, as the name suggests, scripts that are specific to a given application. The OS creates a folder for each application installed, regardless of whether it has any scripts or not.
From what I can read in your picture, the paths given are to /Library/Application Support, not Scripts, which is a different thing altogether.
That is the root level /Library folder, not the one in the user domain. That is where apps may install component files that are essential to their running.
I'd recommend just uninstalling Avast instead.
