Describe the Bug
I have a hybrid gpu laptop with nvidia gpu as /dev/dri/renderD128 and intel igpu as /dev/dri/renderD129. If i choose kms as the capture method for monitor other than 0. I get error like below
I tried the nightly version and the flatpak version with both igpu and dgpu and still faces the same issue. I was able to use kms for monitor 0. Also note x11 and wlroots capture methods work on external displays, the issue was only with kms capture.

I'm getting the same issue - it worked on previous builds e.g. 0.21.x I'm using the same driver version, 550.67 - on an RTX 3070 (Pop OS) Also tried nightly builds and the issue persists across flatpak, deb, AppImage

I tried this version, but has the same issue. Are you facing this on external monitor (monitor 1) and also using kms capture?
Sometimes the internal display and the external display outputs are not connected to the same GPU. I have an Asus laptop where the internal display is connected to the iGPU (or a mux) but the HDMI port is connected directly to the dGPU. That has implications for which GPUs can be used to encode each output (since GPUs generally don't support importing images with a different vendor's special tiling modifiers).
I suspect part of the problem is that you've specified an incompatible combination of encoder, adapter_name, and output_name in your config. I recommend starting over with all options at defaults, then try setting output_name alone. See if you get further that way.
I tried doing this. But if i use KMS capture no matter which GPU I use or leave it to the default setting , results in the above error. And its only a KMS issue since i was able to use X11 and wlroot capture
I had no issues before because (I'm guessing) KMS wasn't the default option. I had the same problem when in a newer build AV1 was introduced and set to "advertise based on encoder settings" which didn't work. Once I set it to not advertise support it worked fine.
X11 still works fine for me, it just falls over because of KMS capture. I'm also on a desktop with a 5800X3D, so no iGPU.
