Thank you for choosing Photon!
Not sure what's wrong but this is probably an issue with Visual Studio integration (or the Editor you are using), or the Unity project itself or the Unity version.
Try rebuilding the C# projects or creating another project (new fresh empty one) or changing to another Unity version.
