    Just looking at the exception trace you can see the exception you got was caused by a TypeInitializationException which means an exception occurred while trying to load a type at startup. Going further down the exception chain there is an exception trying to set up IdentityServer. Following it further it appears to be an authentication/connection issue. The stack trace shows KeyVaultCredential which leads me to believe either there is a credential that is bad or it cannot get to KV. You'll probably need to dig into your logs to ensure everything is configured properly.
