This is what I did to fix the OBS open and close issue after the Jan 25, 2023 patching issue.
I think the main concept is reinstalling the Nvidia drivers and reboot. That is, strip the Nvidia drivers, reboot, install video-linux driver, reboot, re-install Nvidia drivers, reboot, remove the video-linux driver, reboot. Then OBS works with Nvidia drivers with the Jan 25, 2023 patches.
Notes:
I did wiped my Manjaro OS and re-install it with the open source drivers initally, but you can skip this step because OBS still broke after a post wipe full patching reboot. I am not sure if this huge step made a difference.
And I used the mhwd auto propietery Nvidia GPU drivers and open source video-Linux drivers via the Manjaro Setting HW GUI install tool (not the Nvidia drivers by downloading from Nvidia’s site CLI “make” methods).
Hope this helps.
