ScreenDeck 1.2.0 does not connect to Companion Betas 4.0.0+7.9.1.5 or 4.0.0+7.9.1.9

Describe the bug
I'm starting to test the new Companion betas and in both 7.9.1.5 and 7.9.1.9, ScreenDeck 1.2.0 will not respond to anything and the buttons do not change.

To test this, have ScreenDeck running in Companion 3.5.3.... Upgrade Companion to 4.0.0+7.9.1.9. At that point, even though the status screen shows that it is connected, ScreenDeck will not respond to any key presses, it shows the status that was last shown while connected to 3.5.3 and neither stopping the instance of ScreenDeck or restarting Companion will allow it to connect and respond. The only solution I've found is to downgrade Companion back to 3.5.3.
