Thank you, that is quite helpful, and confirms my own suspicions. However, I would like to stay on Monterey because I have to many VSLs and programs that would probably not survive the update to the current OS. But updating even to Monterey 12.7.6. could do the job. Where can I find an update for that? Plus, is it possible to reinstall an earlier version of the Unarchiver, so that it runs again on my current OS?

How to get old versions of macOS
Safari will open a redirect and open the Apple Store where the download can commence.
Suggest having at least 50 GB of Empty Space on the drive.
It will allow the Full Version ( about 12.xx GB ) to download, then expand and then commence to install.
If there is Third Party Security Software installed - remove it.
It will interfere with both the download and installation process.
