Seems like one of the recent NVIDIA driver updates stops the game from working, as a few weeks ago it has been working just fine, but now I had to switch the NVIDIA driver to the 535 version through AUR for the game to work. Before downgrading the driver, launching the game with DX12 caused it to crash during initial loading (the gray bar one), while using Vulkan caused the game to freeze during the same loading screen without crashing (all progress has stopped after a few seconds, according to the RAM usage). After downgrading the driver, the game runs flawlessly.
