jomada yes, there was a user on IRC that could help me with nvidia 435, since I don't have the hardware to test, so the version in build is tested to work again, 430.50 was tested to work too, but did you encounter on update issue? Might have pulled in nvidia-bumblee-utils..., thus kdeinit5 will fail. If you pacman -Sdd nvidia nvidia-utils all should work, but correct version will move soon to all users.
Also means a new ISO will be needed soon.
