Biometrics are a bit misleading as it's not a new problem. You simply don't have any compiler installed and you need one to use loadlibray (or they should provide a proto file).
On the other hand, the error message is very clear and tells you how to fix the problem. Follow its instructions to install minGW-64. Alternatively, you can install any other supported compiler such as Visual Studio (2013, 2015, 2017 but not 2019 for your version).
