Insteon Integration breaks on core-2021.8.0 - 8.3!

The built in integration for Insteon breaks with core-2021.8.0 and above

It no longer connects to the Hub 2 / Modem sort of. Worked fine in core-2021.7.4. Now no matter what I do, it will not connect to the Hub 2 making all my Insteon devices no longer useable. It connects to the hub I guess, no errors but nothing changes or connects.

Unlike last time where it just outright would not connect to the hub, the devices claim to be present but not actually connected and nothing actually works or can be controlled any longer.

All Insteon devices just state not connected and are unusable!
