InvalidOperationException: Could not execute the method

Hello. I am sorry to bother you. When I started my application, it showed an error messages like below. but sadly It just said "Filename: Line: -1", so I couldn't know which points has error. I guessed Unity Player tried to execute something before it loaded completed. is there any options or solutions for this?

it doesn't make application crashed. but it is really annoying to me. how can I fix it?

 

you mean the "Development build"? yes I checked the development build option

 

I will try. but the error message occured when the application started. this messages showed while the unity logo came out

 

I'm getting this as well, in 2019.3.14. It actually does crash if using IL2CPP. This seems to be a recent bug, the only other reference I can find is someone else's game

Any updates on this?
I'm having it too on version 2020.1.8

I realize this is an old thread, but I when I build my game I am receiving a similar error.

Doesn't cause the game to crash, but it seems as if many gameplay elements relating to custom interfaces and scriptable objects are completely broken in the game and just don't function (Null Ref Exceptions further in the logs). Investigating myself, and not quite sure where to look for more help on this, but can certainly provide more details if needed.

Any traction on this issue in recent months?

I am getting this on Windows and Linux builds too, only in builds.

 

Same only in build in 2021.1.21

 

I tracked it down coming from an

[InitializeOnEnterPlaymode]

used to reset a static Dictionary in a struct. It's probably the same case for RuntimeInitializeOnLoadMethod in builds, didn't tested it yet.

Code (CSharp):

1.  
2. // part of non-static struct type
3. private static readonly s_Dictionary<int, SomeValue> s_Dictionary = new Dictionary<int, SomeValue>();
4.  
5. #if UNITY_EDITOR
6.     [InitializeOnEnterPlayMode] // <-- uncommenting this removed the error in the Editor
7. #else
8.     [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]
9. #endif
10. private static void ResetOnLoad()
11. {
12.     s_Dictionary.Clear();
13. }

The Doc states it can be used for Editor-CLASS methods, so structs doesn't seem to be supported.
https://docs.unity3d.com/ScriptReference/InitializeOnEnterPlayModeAttribute.html

Update, made it a class to test it, still get the error, so forget what I've written about the struct, but still only happens when the attribute is not commented out.

 

Okay, I found the issue, for anyone stumbling upon this thread here's what caused this in my project:

I had a generic struct with a static field to be reset, I guess unity tried to call the function for sth like SomeStruct<int> but the "containing"-type SomeStruct<T> was not "instantiated"/parsed whatever magic happens there, yet:
"Could not execute the method because the containing type is not fully instantiated."

So after thinking it may not work with structs I tried it with a class, same issue.Since the field to be resetted had nothing to do with the generic-type I separated both and made the non-generic part an abstract base class to be inherited from a derived generic child-type.
With now the reset-code inside the abstract base part the error no longer occurs, and is called correctly, ofc this wont work with structs, since they only can inherit interfaces. Here's the dummy code I used to check how I can work arround that:

Code (CSharp):

1.  
2.     // works
3.     public struct SomeStruct
4.     {
5.         private static int s_fieldToReset = 0;
6.    
7. #if UNITY_EDITOR
8.         [InitializeOnEnterPlayMode]
9. #endif
10.         private static void ResetOnLoad()
11.         {
12.             s_fieldToReset = 0;
13.         }
14.     }
15.  
16.  
17.     // causes the exception (also if it's an struct doesn't matter):
18.     public class SomeGenericClass<T>
19.     {
20.         private static int s_fieldToReset = 0;
21.         private T someOtherThing;
22.    
23. #if UNITY_EDITOR
24.         [InitializeOnEnterPlayMode]
25. #endif
26.         private static void ResetOnLoad()
27.         {
28.             s_fieldToReset = 0;
29.         }
30.     }
31.  
32.  
33.     // combination of the following works though:
34.     public abstract class SomeBaseClass
35.     {
36.         private static int s_fieldToReset = 0;
37.    
38. #if UNITY_EDITOR
39.         [InitializeOnEnterPlayMode]
40. #endif
41.         private static void ResetOnLoad()
42.         {
43.             s_fieldToReset = 0;
44.         }
45.     }
46.  
47.     public class SomeGenericClassThatWorks<T> : SomeBaseClass
48.     {
49.         private T someOtherThing;
50.     }

What you might want to test (I didn't) is whether it works if you keep the

SomeGenericClass<T>

that causes the exception above and try to define a concrete derrived type, maybe Unity/TheCompiler can interpret this correctly in that case idk:

Code (CSharp):

1. public class ConcreteClass : SomeGenericClass<OtherType>
2. {}
