The only possible explanation, given what you've shown us, is that your code threw an error bad enough to crash the .NET CLR. There is no way for us to figure out that that was. That string is just garbage. It's not a hash and has no meaning at all. First things first. Can you reproduce the error on another machine? Next, I hope you know how to use WinDbg. If not, read Quick start to using WinDbg[^], and Get Started: Debugging Memory Related Issues in .Net Application Using WinDBG and SOS[^], and .NET Crash: Managed Heap Corruption Calling Unmanaged Code[^] Oh, and as a sidebar, hashes are not-reversible...
