C++ FIPS issue

Whenever I try to start a UE4.22.3 C++ project, it get an error. UE tells me that it can’t be compiled and asks if I’d like to open it in Visual Studio (using VS 2019 - 16.2.0). I get the error that there’s a “System.InvalidOperationException: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms”. I eventually get the same error if I start a regular or blueprint project, add C++, close out, and then try to restart the projects after adding the C++ code.

I saw this on a few other forums and the answer seemed to be to turn off FIPS, but turning FIPS off is not an option for me. Any other suggestions?

Did you ever figure out what this issue was? I am having a similar issue but I don’t have FIPS enabled.
