Multiseat gaming with two identical RTX 3060s on EndeavorOS

Hello y'all!

I'm trying to launch the game Star Citizen, and I get the error below:

Assersion failed!

Program: C:\windows\system32\winevulkan\vulkan.dll
File: ../dlls/winevulkan/loader.c
Line: 664

Expression: !status

For information on how your program can cause an assertion failure, see the Visual C++ documentation on asserts

(Press Retry to debug the application - JTT must be enabled)

I have three options:

• Abort, which brings me back to the launcher and asks if I want to retry launch or verify the game files
• Retry, which encounters the same error again
• Ignore, which closes the window, but the game does not start despite the launcher stating that the game is running

Distro: EndeavorOS CPU: Ryzen 9 5900X RAM: 64GB GPU: Two Identical RTX 3060s

I currently have the PC configured for multiseat, where the system has two RTX 3060s, and two monitors/sets of peripherals. I used loginctl to assign seats.

I have two separate installs of the game, both in the default install location (/home/user/Games), for both myself and the second user on the system (for two simultaneous logins).

Wenever I open Lutris and go to system options, the Vulkan ICD loader dropdown menu only shows "Unspecified: Not Found (default)", and "Nvidia Proprietary: Not Found"

I tried this previously with Kubuntu, and I got the same error, but only on seat0. The game launched and ran fine on seat1. When checking the system settings in Lutris, it showed one selection for one of the RTX 3060s on both users.
