Can't boot or recover my macOS

Hey guys,

I have a 2015 iMac which until today was running OCLP with Sonoma. After Sonoma update yesterday I got prompted about the root patches that are necessary. After rebooting the system freezes at 1/3 of the loading bar and green lines appear at the top. I tried using the "Recovery 14.4.1 (dmg)" but it goes into a black screen and then reboots. The recovery with cmd+R, cmd+option+R etc. don't seem to work. What can I do in this situation? I'm thinking about using a USB recovery but are there other options?

Thanks!
