All of the following criteria must be met

• All Requirements must be installed.
• Full Latest.log file included. If no file exists then leave this unchecked and state so.

All of the following are optional to answer

• Tried reinstalling the Game.
• Tried reinstalling MelonLoader.
• Tried restarting PC.
• Was able to see the Start Screen.

Describe the issue.

As you can see from log there exist an error and i guess because of tat I cant even load mods. Game launches fine even loads to save but no mods.
MelonLoader_23-01-29_18-26-35.794.log

Did you attach your log file?

• Yes, I attached my log file to the text box above.
• No, I could not find a log file at {Game_Directory}\MelonLoader\Latest.log

For what it's worth, I was experiencing that error in beta 0.5.7 but I'm not in alpha 0.6.0. I am however, experiencing a different error in 0.6.0:

[08:32:21.616] [Il2CppAssemblyGenerator] Error Generating Interop Assemblies! System.NullReferenceException: Object reference not set to an instance of an object. at Il2CppInterop.Generator.Contexts.AssemblyRewriteContext.RewriteTypeRef(TypeReference typeRef) in /home/runner/work/Il2CppInterop/Il2CppInterop/Il2CppInterop.Generator/Contexts/AssemblyRewriteContext.cs:line 133 at Il2CppInterop.Generator.Passes.Pass12FillTypedefs.DoPass(RewriteGlobalContext context) in /home/runner/work/Il2CppInterop/Il2CppInterop/Il2CppInterop.Generator/Passes/Pass12FillTypedefs.cs:line 33 at Il2CppInterop.Generator.Runners.InteropAssemblyGeneratorRunner.Run(GeneratorOptions options) in /home/runner/work/Il2CppInterop/Il2CppInterop/Il2CppInterop.Generator/Runners/InteropAssemblyGenerator.cs:line 79 at Il2CppInterop.Generator.Il2CppInteropGenerator.Start() in /home/runner/work/Il2CppInterop/Il2CppInterop/Il2CppInterop.Generator/Il2CppInteropGenerator.cs:line 30 at Il2CppInterop.Generator.Il2CppInteropGenerator.Run() in /home/runner/work/Il2CppInterop/Il2CppInterop/Il2CppInterop.Generator/Il2CppInteropGenerator.cs:line 47 at MelonLoader.Il2CppAssemblyGenerator.Packages.Il2CppInterop.ExecuteInterop() in D:\a\MelonLoader\MelonLoader\Dependencies\Il2CppAssemblyGenerator\Packages\Il2CppInterop.cs:line 97

But I don't want to hijack this ticket so I'll leave it at that - looks like both mine and OP's errors are pointing to the assemblies - potentially the same cause?

im having the same error,

Also this ticket looks to be a duplicate of #378

As of just now, 0.6.0 should work on Farthest Frontier.

nope here you go with the latest log all other mods also have same error
Latest.log
Latest.log

Yes it's working now without errors. I had to do a few extra steps to get my mods to work correctly:

• Update the mod to .NET 6 framework (as stated on the wiki)
• Reference assemblies in the MelonLoader/Managed folder (as stated on the wiki)
• Reference assemblies in the MelonLoader/net6 folder
• Update my mod's references
• Replace UnhollowerLib references with Il2cppInterop.Runtime

Please update the wiki guide to include the third line as it's needed for il2cpp based games.
