Came here to make a little PSA about this exact issue, but it seems like you beat me to the punch!

Kinda surprised they released them out of sync like this tbh.

Thank you! "enable multilib-testing and update lib32-nvidia-utils" fixed it for me too.

Yep, thanks for letting us know. On another note: How many of you had the annoying screen flashing on Wayland and had to downgrade anyway? Apparently it happens in Wayland sessions while using a high refresh rate. I've had flashing in Sway with Nvidia for a while unless I use a very specific version of sway-git. But this (after upgrading the Nvidia drivers to 535) is way worse.
