The causes for this issue can be numerous. This might be shooting in the dark, but try removing the bin and Debug folders from the project that is causing the issue and then try and rebuild. If the problem persists, could you please try and isolate the issue in a separate project and send us the project so we can debug it locally. If that is not an option you can record a video and share it with us. This way we will be better able to assist you.
