After "finishing" patch, not launching game on Arch Linux, DXVK failed to create instance

[yaomtc]

Dawntrail install/patch process seems to have finished but I suspect something went wrong with it, as the game will no longer launch with XIVLauncher. Here is the output. (This occurs both with the Flatpak version on Flathub and the XIVLauncher.Core-arch.tar.gz build of 1.1.0)

[bugQ]

Have you tried launching with the official launcher at least once since patching? There is a new EULA that must be accepted and will only display there.

The EULA does not matter. It's only used by the official launcher before anything login-related.

This looks more like DXVK is failing. Do you have a working vulkan provider / up to date GPU drivers?

You also cannot switch between the flatpak and a native build without resetting wine and the wine prefix, or you'll run into other issues.
