No internal display output, external display works, after kernel update 6.3.9 -> 6.4.x

After an upgrade to the latest kernel, 6.4.3.arch1-2 at the moment of writing the issue, there is no display output on the internal monitor of the laptop. I tested with an two external display through either the HDMI port or via USB-C [displayport mode] respectively and it does display an output with no apparent issues (e.g. lag or weird flickering). I have attached the dmesg output with debug information as per the wiki instructions, also attached the edid as per the related issue #8789 (closed) . I will test the drm-tip and report on whether the issue resolves.

System Architecture: x86_64
Linux distribution: Archlinux
