Communication port managed and unmanaged code

Ok this is a bit of a shot in the dark hoping someone out there can help as I am at a loss for what to do or how to fix the issues. I have read all MSDN and to the best of my knowledge coded all requirements. The driver is coded in C and the user application or client is coded in VB.NET so interacting between unmanaged and managed code is probably the reason I am having so many issues here. the driver builds fine and runs fine when the client application is not being used but if I try to block and allow processes or use FilterGetMessage, FilterReplyMessage the OS becomes stuck and I am forced to restart the VM. I have Uploaded the project to my one drive here is the link

The Functionality I wish to acheive is to monitor process creation using the driver. The driver will use fltsendmessage to deliver the file path to the client application and wait for a reply to either block or allow the process. Nothing at the moment seems to be working :(
