The only thing I can suggest than is to try to debug the problem. I would first try to use procmon from the sysinternals suite to determine what API calls are made when the library is loaded into Racket, which one returns an error and what are the parameters to that call. I would also use dependency walker to determine what other DLLs are used by libgit -- sometimes a DLL fails to load because some other DLL it depends on is missing or corrupted, but when that is the case, the error messages are very confusing.
