27" late 2013, OCLP 1.3, Sonoma 14 with blinking / freezing login screen

Hi,

Same issue, The iMac starts blinking at the login screen and can't type the password as it resets the screen and freezes every 2-3 seconds. And when wake from sleep mode, the screen doesn't respond anymore.

I have a 27" late 2013, using OCLP 1.3.0 with Sonoma 14.1.2 (Tried 14 , 14.3 ...)
