Frida il2cppbridge access violation when trying method Add or Insert at System.Collections.Generic.List`1 (List<int>)

I am using Frida il2cppbridge and having the problem that I'm getting always access violation error when trying to add values to generic list. What I'm doing wrong?

let list = Il2Cpp.corlib.class("System.Collections.Generic.List`1")
let int = Il2Cpp.corlib.class("System.Int32")
let listInt = list.inflate(int).new()
                     
listInt.method(".ctor").invoke()
listInt.method("Add").invoke(1)

or also if I get the list from internal like:

// return type is List<int>
let list = anyClass.method<Il2Cpp.Object>("getList").invoke()
                     

list.method("Add").invoke(1)

Getting always the same error, doesn't matter if I try method Add, Insert or set_Item

Error:

access violation accessing 0x3e8
at invokeRaw (il2cpp/structs/method.ts:233)
at (src/index.ts:18)
at call (native)
at (il2cpp/structs/method.ts:354)

Methods like get_Count works fine.
