[Bug]: Game crashes without any log entry

startrekfleetcommand-dev commented 5 days ago

All of the following criteria must be met

[X] All Requirements must be installed.
[X] I have searched the GitHub issues for my bug, even in the closed issues.

All of the following are optional to answer

[X] Tried reinstalling the Game.
[X] Tried reinstalling MelonLoader.
[X] Tried restarting PC.
[X] Was able to see the Start Screen.

Describe the issue.

With 0.6.5 on Windows 11, the game gets to a loading screen but consistently crashes silently, even when no mods or plugins are installed. With the example plugin it shows that OnInitializeMelon fires, but nothing after (OnGUI, OnUpdate etc.) No errors in Latest-Bootstrap.log either. Tried with AVG off, and in safe mode. Latest nightly as well, same thing.

Event Viewer shows exception code 0xc0000005 in GameAssembly.dll , which Microsoft's Debug Diagnostic Tool describes as an access violation.

Had to move off of the rock solid 0.6.3 as it (and all versions before it) have Il2CppAssemblyGenerator throwing the following:

Cpp2IL.Core.Exceptions.LibCpp2ILInitializationException: Fatal Exception initializing LibCpp2IL! ---> System.FormatException: Unsupported metadata version found! We support 23-29, got 31

Weirdly the latest bepinex 6 can load into the game with the sample mod without errors, but it lacks the OnGui and OnUpdate functionality.

Did you attach your log file?

Yes, I attached my log file to the text box above.

Give the latest alpha-development build of v0.6.6 a try and let me know if you have the same problem. https://nightly.link/LavaGang/MelonLoader/workflows/build/alpha-development

Latest.log

Thanks for responding! Tried both x64 Release and Debug there, in clean installs, and they fail in the same spot. Same 0xc0000005 in GameAssembly.dll . Anything else I could try?

Redownload the alpha-development build of v0.6.6 from the same URL and try again. We have just made more changes that might help more. https://nightly.link/LavaGang/MelonLoader/workflows/build/alpha-development/MelonLoader.Windows.x64.CI.Debug.zip

Thanks for staying on this! Same issue in a clean install with no mods unfortunately - 0xc0000005 in GameAssembly.dll . I've highlighted the changes to the most recent Debug.log using Beyond Compare (Latest-Bootstrap.log is the same)

Latest.log

Please keep looking, and I'll keep trying!

Been wondering if its something in the binaries of the latest game update causing the crash, aka attempts to block external loaders/libraries etc, so found a pre-update copy of the game with 0.6.2 installed. It still runs without crashing, and stops with the expected "You need to update your game" screen (process stays executing, my mod loads great, no appcrash or uncaught exception).

Keeping the pre-update copy of the game, removing the 0.6.2 Melonloader folder and emptying the Mods and UserLibs folders, and then installing 0.6.4, 0.6.5 and latest alpha 0.6.6 all yield the 0xc0000005 appcrash in the GameAssembly.dll

I mentioned "the rock solid 0.6.3" in my initial post. I meant to say 0.6.2 was rock solid. In the above scenario 0.6.3 fails early with the following (typed out from a screenshot, not present in Latest.log):

[NewEntryPoint] Passing ptr to LoadAssemblyAndGetFunctPtr back to host... [NewEntryPoint] Configuring imports... [NewEntryPoint] Initializing. In default load context: True [!] [C:\Users\Sam\CLionProjects\Dobby\source\InstructionRelocation\x64\X64InstructionRelocation.cc:86:GenRelocateCodeFixed]: [!] unimplemented code!!!

I really hope this helps nail down when the issue could have crept in.
