I ended up using another mac and dfu mode. Reviving did not work, so I ended up restoring (erase+install).

I have the same issue. I turned off pro-motion to avoid the windowserver memory leak. I applied the latest ventura uprade and now my laptop is essentially bricked. I see the apple logo, or startup options if I hold the power key, but in all instances the screen goes blank and the mac becomes unresponsive. I can't see it on my network and attempting to login in 'blind' doesn't work either.
I've scheduled a support call for tomorrow am and a 'genuis' bar visit also and I'll update the thread.
