Symptoms

The game will fail to start with the following message:

System.UnauthorizedAccessException: Access to the path "SNIP\steamapps\common\Proxy Blade Zero[Unknown]" is denied.

Where [Unknown] is coming from I'm not sure, but it seems to be okay otherwise (including the Forms launcher).

  1. Start game with default settings
  2. Messagebox
  3. Exit

Update using proton Experimental on a 512 GB Steam Deck. Game successfully starts now, but I only see a black screen, music still plays and menu noises can be heard when moving the stick. Launching with or without the launcher makes no difference.

Still an issue as of the latest Experimental Proton build.

Still occurring as of latest Experimental

Still occurring on latest nightly using my OLED Deck, happens on both game mode and desktop mode

Still borked as of latest nightly, I ran a new log to check if anything new popped up, but between checking my new and old log, I noticed this error, appearing multiple times which I'm unsure if it's related to the issue.

00000130:] EXCEPTION handling: System.NotImplementedException: Unhandled render state! 165

Could be, looks like it's from FNA: https://github.com/FNA-XNA/FNA/blob/99a5b2100110592f7ef998c509dbb57006983085/src/Graphics/Effect/Effect.cs#L610

I'm guessing this issue should also be brought up on the FNA github then, since that seems to be where the issue is occuring?
