Can someone help me interpret the following log entry? "ERROR org.springframework.web.context.ContextLoader - Context initialization failed"

Hello Appian Community,

My team and I are in the process of installing Appian version 22.4 on Windows 2016 Standard with IIS 10 and MS SQL Server 2016 Enterprise Edition. After following the steps from the guide and attempting to start the app and all its components (Service Manager, Data Server, Search Server, app) we get an error in the logs that ends with this entry

2023-08-11 13:39:10,957 [localhost-startStop-1] FATAL com.appiancorp.common.web.StartupHaltingServletContextListener - Appian initialization FAILED: see above stacktrace for details

and starts with this entry

2023-08-11 13:39:10,935 [localhost-startStop-1] ERROR org.springframework.web.context.ContextLoader - Context initialization failed

Here is an excert of the rest of the message:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.filterChains': Cannot resolve reference to bean 'org.springframework.security.web.DefaultSecurityFilterChain#66' while setting bean property 'sourceList' with key [66]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.web.DefaultSecurityFilterChain#66': Cannot resolve reference to bean 'preBasicAuthFilter' while setting constructor argument with key [6]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'preBasicAuthFilter' defined in ServletContext resource [/WEB-INF/conf/security/spring-security-05-web-api.xml]: Cannot create inner bean 'util:list#63df5958' of type [org.springframework.beans.factory.config.ListFactoryBean] while setting bean property 'filters'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'util:list#63df5958': Cannot resolve reference to bean 'oAuthFilter' while setting bean property 'sourceList' with key [0]; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.appiancorp.oauth.inbound.resourceserver.security.OAuthFilterSpringConfig': Unsatisfied dependency expressed through field 'oAuthInboundProductMetricsLogger'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.appiancorp.oauth.inbound.OAuthInboundSpringConfig': Unsatisfied dependency expressed through field 'suiteConfigurationAdapter'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.appiancorp.oauth.inbound.OAuthServiceAdapterSpringConfig': Unsatisfied dependency expressed through field 'certificateService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'certificateService' defined in class path resource [com/appiancorp/security/ssl/SslSpringConfig.class]: Unsatisfied dependency expressed through method 'certificateService' parameter 1; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'systemCryptographerProvider' defined in class path resource [com/appiancorp/security/external/ExternalSystemSpringConfig.class]: Unsatisfied dependency expressed through method 'systemCryptographerProvider' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'keyStoreConfigSupplier' defined in class path resource [com/appiancorp/common/crypto/CryptoSpringConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.google.common.base.Supplier]: Factory method 'keyStoreConfigSupplier' threw exception; nested exception is java.lang.NullPointerException

Has anyone encountered this before or have any insight on what might not be properly configured?

We have gone through the installation steps several times now and have run out of things to look at. If no one has any fix to recommend I would at the very least appreciate getting a better understand of the entry ERROR org.springframework.web.context.ContextLoader - Context initialization failed

Thanks in advance,

Added stack trace and removed the redundant portion.
