Screens not working on Sonoma - 14.0 Beta (23A5276g)

I also have this issue, macOS Sonoma public beta 2. Version 14.0 Beta (23AS5312d).

When I restart my mac, I have to plug an HDMI cable directly into my mac before I am able to log in. The screens remain blank before login otherwise, and this prevents me from logging in.

My USB keyboard and mouse dongle does not work before login as well.

The login extension is not working because of the mac beta, or the display link alpha.
