Try right clicking the game title in your steam library and choosing properties>betas one of the devs (Penta) has just posted that they have uploaded a branched version of the game which many potentially fix the visual issues some are encountering.

A steam user also suggested adding -windowed to the games launch properties might help.

We are very sorry about that! It seems like a very rare issue, but it seems that we have fixed it and an update will be rolling out ASAP!

It’s 2.45 am here in the UK which probably means it’s about 4.45 am in Poland? Thanks very much Artur it pretty obvious you guys are really committed to the success of project and customer satisfaction.

I confirm that the latest few today patches did not bring resolution to the black screen problem after starting the game (((

Some newer games need specific CPU command extensions to run properly and older processors don't have it. Maybe that's the reason?

In a discussion on steam, people write:
My game still doesn't work. Still get the black screen on startup. Its not as if my PC is old and is struggling to run this game. I've got an i9 10900k, 16GB RAM, 3080 GTX Nvidia GPU.

Problem not solved yet.

I'm experiencing this issue too. I've gone through some extensive diagnostic steps and workarounds to no avail, and have even installed the game on two different computers (my desktop and laptop) with the same result: Game launches to indefinite black screen.

These three lines in my Player.log file could be a clue as to why the game menu never loads or outputs any sound:

Code:

NullReferenceException: Object reference not set to an instance of an object.

  at GameManager.get_SpeechVolume () [0x00000] in <00000000000000000000000000000000>:0 

  at MainMenuManager.Start () [0x00000] in <00000000000000000000000000000000>:0

I've attached my full Player.log file, which is located in the directory: "%USERPROFILE%\AppData\LocalLow\Iron Wolf Studio\Destroyer The U-Boat Hunter"

For anyone that has a working game, I'd be interested to see what the Player.log file looks like and what appears after the Daedalic.Dbtool.Client.BannerSystem:Start() line item, as that's where my game appears to be getting stuck.

I think it's either the NullReference section that is causing the main menu and the game itself to fail to load, or the start of the BannerSystem that's causing the hang up.

Here are the diagnostic steps I've taken so far:

Installed latest Windows Updates
Installed latest NVIDIA GeForce Game Ready drivers
Fully uninstalled and reinstalled the game
Installed the experimental-public build
Ran game files integrity verification check
Launched the game executable as Administrator
Cleared the NVIDIA cache folder
Changed the scaling option in NVIDIA Control Panel from "Aspect ratio" to "No scaling"
Ran the game with various command-line flags through Steam, i.e. -windowed, -window-mode exclusive, -screen-fullscreen 0, -force-d3d9, -force-d3d12

System specs—

CPU: AMD Ryzen 5 1600X @ 3.60GHz
GPU: NVIDIA GeForce RTX 2080 Ti
RAM: 16 GB RAM
OS: Windows 10 Pro 21H2 (19044)

I can help, where do I find the player log?

I'm browsing the local files, not finding that file... help!

The AppData folder is usually hidden in Windows. For simplicity, if you copy/paste the following string exactly as it is written in File Explorer along the top bar, it will direct you to the location where the Player.log file exists:

%USERPROFILE%\AppData\LocalLow\Iron Wolf Studio\Destroyer The U-Boat Hunter

See my attachment for a visual image example of where to paste the above string in File Explorer.

Thanks again!

Ah, that worked! Here you go.

edit: spoke too soon, file is too large.

That helps immensely Onkel, thank you!

I have determined the differences between a working game (Onkel's log file) vs a non-working game (my log file). If Artur sees this and can pass it onto the devs:

The following group of text exists in my Player.log file, but not Onkel's, right after the <RI> Initialized touch support. line:

Code:

ArgumentException: JSON parse error: The document is empty.

  at UnityEngine.JsonUtility.FromJson[T] (System.String json) [0x00000] in <00000000000000000000000000000000>:0 

  at GameManager.Awake () [0x00000] in <00000000000000000000000000000000>:0 

  at UnityEngine.GameObject.AddComponent[T] () [0x00000] in <00000000000000000000000000000000>:0 

  at GameManager.get_Instance () [0x00000] in <00000000000000000000000000000000>:0 

  at MainMenuManager.Awake () [0x00000] in <00000000000000000000000000000000>:0 

UnityEngine.GameObject:AddComponent()

GameManager:get_Instance()

MainMenuManager:Awake()

And finally, the following group of text also exists in my log file, and is not found in Onkel's log file:

Code:

NullReferenceException: Object reference not set to an instance of an object.

  at GameManager.get_SpeechVolume () [0x00000] in <00000000000000000000000000000000>:0 

  at MainMenuManager.Start () [0x00000] in <00000000000000000000000000000000>:0

So it appears that my game is having issues reading/parsing an empty or missing JSON file, which results in the game's Main Menu to fail to load. The log file, however, does not indicate the name nor location of the empty or missing JSON file.

Additional diagnostics:

I used Process Monitor (by SysInternals) to capture all file access events when the game is launched. The only three JSON files opened/queried were:

RuntimeInitializeOnLoads.json and ScriptingAssemblies.json
Both files located in *\Steam\steamapps\common\Destroyer The U-Boat Hunter\Destroyer The U-Boat Hunter_Data
Banners.json
File located in%LOCALAPPDATA%\Iron Wolf Studio\Destroyer The U-Boat Hunter\Cache\Banners\BannerCache

However, all three JSON files have data inside of them. Without knowing which JSON file the Player.log file is reporting as empty, I am now unable to continue my diagnostics. Hopefully this information is enough to pass along for a quick resolution.

Thank you.
