MAUI Blazor Cannot EV Code Sign with YubiKey

Question

I am trying to code sign my MAUI Blazor (Windows) app using my EV Code signing cert. I have installed my cert on a YubiKey 5 FIPS device. When I run the below command the app starts to build. Then when it's time to sign the package I am asked for my pin (for the YubiKey). Once the pin is entered I get the below exception.

Command:

"C:\Program Files\Microsoft Visual Studio\2022\Preview\MSBuild\Current\Bin\msbuild" /restore /t:Publish /p:TargetFramework=net6.0-windows10.0.19041 /p:configuration=release /p:GenerateAppxPackageOnBuild=true /p:AppxPackageSigningEnabled=true /p:PackageCertificateThumbprint="KeyThumbprint" /p:PackageCertificatePassword="password"

Exception:

C:\Users\user\.nuget\packages\microsoft.windowsappsdk\1.0.0\build\Microsoft.Build.Msix.Packaging.targets(462,5): error
 APPX1204: Failed to sign 'path/to/my.msix'
. SignTool Error: An unexpected internal error has occurred. [path/to/my/project.csproj]
C:\Users\user\.nuget\packages\microsoft.windowsappsdk\1.0.0\build\Microsoft.Build.Msix.Packaging.targets(462,5): error
 APPX1204:  [path/to/my/project.csproj]

Also, if I try the code singing tool I get the below error:

"Error: SignerSign() failed." (-2146435068/0x80100004)

Code Sign.exe Command

signtool.exe sign /fd sha256 /a /sha1 my_thumbprint "path/to/my.msix"

In the past I have gotten a self signed code signint cert to work. This would indicate that the above command is correct.
