HTTP Error 500.30 (Internal.Cryptography.CryptoThrowHelper+WindowsCryptographicException: The system cannot find the file specified.)

Question

I am trying to deploy the asp.net core Web API to the IIS. This application works perfectly fine on the Visual studio and also when I run the dll using the dotnet command. This application has the certificate for signing the JWT token. After deploying the application to IIS I am getting "HTTP Error 500.30 - ANCM In-Process Start Failure" and I checked the windows log and error message is

Host terminated unexpectedly. Internal.Cryptography.CryptoThrowHelper+WindowsCryptographicException: The system cannot find the file specified.at Internal.Cryptography.Pal.CertificatePal.FilterPFXStore(Byte[] rawData, SafePasswordHandle password, PfxCertStoreFlags pfxCertStoreFlags)......

I checked the file path and file name everything is correct but some reason IIS is not able to load find the certificate file. Also, I checked the permission and it also looks good. Not sure why I am getting this error message

Also, I ran the same application dll file using the dotnet run command where IIS is pointing to but I am not getting any error. I am getting this error only after deployng to IIS.

On startup.cs file and configuration method I am getting error on this line.

var cert = new X509Certificate2("test_cert.pfx", pwdFrmVault);
