MS.Utitlity.Event Error while uploading SPFx app to AppCatalog

Question

I try to add a spfx app(.sppkg file) to SharePoint 2019 on-premise appcatalog. and got the error

Invalid SharePoint App package. Error: The type initializer for 'MS.Utility.EventTrace' threw an exception

Using ULS LogViewer, I found following error stacktrace

Unexpected App Packaging: CreatePackage: Unexpected exception: System.TypeInitializationException: The type initializer for 'MS.Utility.EventTrace' threw an exception. ---> > > > System.Security.SecurityException: Requested registry access is not allowed.

This is working in most SharePoint 2019 environment except one.

UAC(User access control) is set to low on SharePoint server and also checked permission on the default regkey for officeserver at HKLM:\Software\Microsoft\OfficeServer\16 and everything looks good.

Thanks

Hi @Vivek Agrawal ,
This is usually caused by IIS anonymous authentication. If your iis web Application Settings enabled aspnet:AllowAnonymousImpersonation and IIS authentications enabled Anonymous Authenticaion & Asp.net Impersonate, your web app will access HKEY_CURRENT_USER\Software\Microsoft\Avalon.Graphics by user specified in IIS Authentications -> Anonymous Authentication -> Specific User, you should make sure this user(IUSR) has read permission to the registry key. You can try to grant "Everyone" read access on that specific key. You can also disable aspnet:AllowAnonymousImpersonation or disable Asp.net Impersonate.
