Windows TFS Compiled, but crash on every action

[Rhumor]

So, I compiled TFS rev 4233 for 8.7 with microsoft visual.
Worked fine, server starts up, accounts can be created via site..

But any action (except walking around and talking) crashes the server and I get the error (theforgottenserver.exe has stopped working)

How can I solve this?

Thanks

already tried to compile it into debug, and run tfs.exe with a debugger.. but same result
