Philips 65OLED820 | 9070XT | CatchyOS | No signal on optimal (120 Hz) and optimal VRR (up to 144 Hz)

CatchyOS Deck Edition - tested both Gaming Mode and KDE Plasma Desktop

Philips 65OLED820 with Google TV

After installing the newest version from AUR, it works in Standard Philips 65OLED820 mode (60 Hz), but when changing the mode to 120 Hz stable or VRR mode with up to 144Hz, I get black screen with no signal. CatchyOS on standard kernel works in all modes with VRR turned off in system (no option either) with Ybcr 4:2:0 in 4k.

can you upload a dmesg? preferably with echo 0x04 | sudo tee /sys/module/drm/parameters/debug before setting to the high refresh rate mode

With the latest changes, my desktop no longer freezes! Managed to get a dmesg output with debug enabled. I'm in mostly the same situation, Philips 55OLED909, 9070XT Nitro+, I only get a picture in standard mode, 120 and 144 modes don't work either. You should see all failed training attempts, as well as a working one at the very end when I switch the TV to standard.
