Describe the issue.

Why did it say, "[ERROR] il2cpp_init detour failed: Failed to load hostfxr. Please make sure you have installed the .NET 6.0 runtime."?

Did you attach your log file?

Select an option below

because you need to download net 6 runtime, a dependency of melonloader. linked is both x64 or x86 depending on your game, id assume x64 tho
https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/runtime-desktop-6.0.33-windows-x64-installer
https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/runtime-desktop-6.0.33-windows-x86-installer

I did, and it still says it. (x86 btw)

That error does not show if you had the proper desktop runtime installed.
