Keyboard stopped working on Lenovo Yoga Slim 7 ProX (AMD) 14ARH7 (EndeavourOS)

After a recent system update, the built-in keyboard stopped working propperly. I googled the issue, but there seems not to be any known issue. The problem arose on July 29, 2023 after upgrading the system from kernel 6.4.6-zen1-1-zen to 6.4.7-zen1-1-zen. other packages, which were updated on July 29: abseil-cpp-20230125.3-2 alsa-card-profiles-1:0.3.76-2 ca-certificates-mozilla-3.92-1 freeplane-1.11.5-1 glslang-12.3.1-2 gspell-1.12.2-1 gst-plugin-pipewire-1:0.3.76-2 lensfun-1:0.3.4-3 libcamera-0.1.0-1 libcamera-ipa-0.1.0-1 libpipewire-1:0.3.76-2 linux-6.4.7.arch1-1 linux-headers-6.4.7.arch1-1 linux-zen-6.4.7.zen1-1 linux-zen-headers-6.4.7.zen1-1 nss-3.92-1 pipewire-1:0.3.76-2 pipewire-alsa-1:0.3.76-2 pipewire-audio-1:0.3.76-2 pipewire-jack-1:0.3.76-2 pipewire-pulse-1:0.3.76-2 python-yaml-6.0.1-2 virtualbox-host-modules-arch-7.0.10-5 Related posts: https://www.reddit.com/r/archlinux/comments/15dbhzy/latest_kernel_could_break_keyboard_on_some_lenovo/?rdt=34893 In Win11, the keyboard works fine.
