Game unable to boot; stuck at Klei logo

  • Branch: Live Branch Version: Windows Fixed

After I boot the game, the game is stuck at the KLEI logo, and then when I try to click on it, it freezes and unresponds. I've tried everything in the support document. I have Mocrosoft defender deactivated, I don't have OneDrive, I closed all background apps. I've deleted my save files, deleted all the DLCs, and deleted all the mods, and verified the files and even uninstalled and installed multiple times. Basically, I've tried everything, but it's still like this.When I try to run it from Steam, it displays the log shown in player-previous.log. when Steam is open and I try to run it from the folder, it says "Fatal error: another instance is already running" even though I already closed all game instances and there is no difference betweeen "open as administrator" or not. When I close Steam and I try to run it from a folder, it initially opens, but it then launches Steam, and then it displays the log as the same if I directly launched it from Steam again. I'm truly stumped here.

DxDiag.txt Player.log Player-prev.log


Steps to Reproduce

First Scenario (Player-prev.log)

Open Steam 

Click "Run Game"

Second Scenario (Player.log)

Open Steam

open Game root folder

double-click OxygenNotIncluded.exe

DxDiag.txt

A developer has marked this issue as fixed. This means that the issue has been addressed in the current development build and will likely be in the next update.

When you uninstalled did you make sure the folder was deleted? I've seen this before where the StreamingAssets folder is not properly cleaned up.

Try deleting:

B:/SteamLibrary/steamapps/common/OxygenNotIncluded/OxygenNotIncluded_Data/StreamingAssets

And verifying files.

Wow! That worked immediately, thank you so much! 

The entire B:/SteamLibrary/steamapps/common/OxygenNotIncluded folder was deleted when i uninstalled the game via Steam, and then i reinstalled it and followed your instructions and the game loaded.

After uninstalling and confirming the install folder was deleted did the game still crash until you removed StreamingAssets and verified files?
