Signing single project app using msbuild not working

[harvinders]

Whilst trying to generate a msix package from my simple project based on the WinUI3 project template (latest) in VS 2022 using following command I get an error
Cannot import the key file 'c:\programs\certificate.dev.pfx'. The key file may be password pro tected. To correct this, try to import the certificate manually into the current user's personal certificate store. .

However, it works on my old two project solution (wapp) without issues.

Just wondering, if it is expected or am I missing something?

msbuild Platform.Raya.sln /p:Configuration=Release /p:Platform=x64 /p:UapAppxPackageBuildMode=SideloadOnly 
/p:PackageCertificateKeyFile=c:\programs\certificate.dev.pfx /p:PackageCertificatePassword=<SomePassword> 
/p:GenerateAppxPackageOnBuild=true /p:PublishReadyToRun=false /p:AppxPackageDir=Installer\
