InvalidCastException: Specified cast is not valid.

Hi, I'm trying to export data from the Memory profiler and I run into this issue.

InvalidCastException: Specified cast is not valid.
ProfilerDataExporter.SplitterState..ctor (System.Single[] relativeSizes, System.Int32[] minSizes, System.Int32[] maxSizes) (at Assets/Editor/UnityWrappers/SplitterState.cs:31)

Any help? Thanks!

Hi there, I was having the same issue with Unity 2022.3.10f1, and fixed it by adding some validations before returning values in UnityWrappers\SplitterState.cs, this are the methods I've modified:

SplitterState.cs Ln25:

public SplitterState(float[] relativeSizes, int[] minSizes, int[] maxSizes)
        {
            splitter = SplitterStateType.InvokeMember(null,
            BindingFlags.DeclaredOnly |
            BindingFlags.Public | BindingFlags.NonPublic |
            BindingFlags.Instance | BindingFlags.CreateInstance, null, null, new object[] { relativeSizes, minSizes, maxSizes });
            realSizes = Array.ConvertAll((float[])RealSizesInfo.GetValue(splitter), x => (int)x);
        }

SplitterState.cs Ln68:

        public int splitSize
        {
            get
            {
                var splitSize = SplitterStateType.InvokeMember("splitSize",
                    BindingFlags.DeclaredOnly |
                    BindingFlags.Public | BindingFlags.NonPublic |
                    BindingFlags.Instance | BindingFlags.GetField, null, splitter, null);
                return splitSize is int intValue ? intValue : 0;
            }
        }

@steve3003 would be amazing to add it on the next version if you are updating it any time soon.
