Description
My Custom Credential Provider "XCP" is not working on EC2 instance. I used this code base (https://github.com/microsoft/Windows-classic-samples/tree/main/Samples/Win7Samples/security/credentialproviders/samplecredentialprovider) for developing the XCP. The windows application "LogonUI.exe" tries to invoke XCP and fails, so I'm unable to log into my VM. I have tested it over multiple machines and it works fine but only cloud based VMs are failing.

Research direction
Start with the linked SampleCredentialProvider code and Report.txt, then compare LogonUI.exe behavior on the affected EC2 and Azure VMs with machines where XCP works. Done means identifying and documenting the cloud-specific cause of the crash and confirming that the custom provider no longer prevents VM login.
