Can not Sign the MSIX pacakge with self-signed certificate

I used Makeappx tool to convert my appx package to the msix package and now I want to test my msix package. I created a self-signed certificate by following the steps from https://docs.microsoft.com/...

Hi,

Yes, I have the same issue:
SignTool Error: An unexpected internal error has occurred.
Error information: "Error: SignerSign() failed." (-2147024846/0x80070032)

Event viewer show me this: "The reader was created successfully without manifest validation." And it is under Information Level, not Warning or Error.

Details:
MSIX create with MSIX Packaging Tool (Preview)
OS build: 17713.1000
Signtool.exe used from C:\Program Files (x86)\Windows Kits\10\bin\10.0.17134.0

Toms Knostenbergs sounds like you are using signtool to sign the package, is that correct? Can you please try to convert the package again using the MSIX Packaging Tool and add your test certificate in the last page of the wizard to have the tool sign the MSIX package? If you hit the same error please file a feedback hub problem from the error pop up so we can take a look at your logs.
