IOS Project Deployment Failing

I have tried to deploy my IOS project multiple times but it keeps giving me an error. I have the certificates and provisions imported in and it says they are valid. When I deploy it, it gives me this at the end.

LogPlayLevel: IPP ERROR: Application exception: System.Security.Cryptography.CryptographicException: Invalid provider type specified.
