I would also be willing to help test the modifications to the All-In-One-Installer so we can continue to update it with future modifications to Home Assistants!!

The key thing here is that you can keep upgrading, it simply doesn’t work for new installs.

Now, instead of any of those steps you tried, maybe you’ll find just upgrading Python (and the virtual environment) easier?
