I have the same error with the same method and versions of BepInEx and VRising 1.0!
Maybe the Error Log also helps:
Unhandled exception. System.IO.FileNotFoundException: Could not load file or assembly 'UnityEngine.CoreModule, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'. Das System kann die angegebene Datei nicht finden.

I can confirm, I have the same issue using the latest V Rising, downloaded from here.

Looks like it's based on some dotnet variant instead of mono, not 100% sure what needs to be done to update BepinEx to run with dotnet. Might be using an outdated BepinEx 6 version.

Even if you do manage to get past this error, It has to do with type registrations as near as i can tell - ClassInjector.RegisterTypeInIl2Cpp will immediately trigger a crash. Given even other projects like UnityExplorer fall victim to the same thing.

[demonkid13579]

well the game has updated to 1.0 may 8th so might be out of date

[Marinxar]

Definitely the update. Just got to hope they get time to update soon ^^

[das-eisen]

Same shit. I've been looking for a solution for two hours, but I haven't found anything (

[NeonOby]

The solution is to either wait for the VRising Community to fix BepInEx and the mods you want Or to help them if you are a programmer that can.
Search for "vrising mods wiki" should be the first link, there is a discord and pages about the 1.0 update.

Anyway this also seems to be a problem with BepInEx which is not updated for the latest Games build with Unity.
So this probably will happen with more games in the future if BepInEx isn't updated.

Client crashed at the start too:
[Error :InteropManager] Failed to generate Il2Cpp interop assemblies: Cpp2IL.Core.Exceptions.LibCpp2ILInitializationException: Fatal Exception initializing LibCpp2IL! ---> System.Exception: Failed to find Binary code or metadata registration
Tried both IL2CPP or mono from latest bleeding edge builds from
https://builds.bepinex.dev/projects/bepinex_be
no results
