Issue: Steam crashes on launch when using NVIDIA 340 drivers

These are the nvidia packages I have installed:

lib32-nvidia-340xx-utils 340.108-1
lib32-opencl-nvidia-340xx 340.108-1
nvidia-340xx-dkms 340.108-37
nvidia-340xx-settings 340.108-2
nvidia-340xx-settings-debug 340.108-2
nvidia-340xx-utils 340.108-1
opencl-nvidia-340xx 340.108-1

This is steam running with a debugger, gdb:

Steps for reproducing this issue:

1. Install Arch Linux, latest kernal with headers and all proper packages
2. Install nvidia version 340 drivers, prevent nouveau drivers from being loaded on boot
3. Install and run steam through Flatpak or AUR, do not install present version nvidia-utils, as that breaks nvidia-340xx-utils, same with lib32 package
4. Run Steam, observe crash after initial update
