Issue description:

Seems UWP export does not work. It is generates damaged file, that I can't run.

And signtool can't sign file.
`C:\Program Files (x86)\Windows Kits\10\App Certification Kit>SignTool sign /fd SHA256 /a /f c:\key.pfx /p x D:\System\Documents_GODOT\Export\UWP\green_pixel.appx
Done Adding Additional Store
SignTool Error: This file format cannot be signed because it is not recognized.
SignTool Error: An error occurred while attempting to sign: D:\System\Documents_GODOT\Export\UWP\green_pixel.appx

Number of errors: 1`

Steps to reproduce:
Try to export to UWP and run.

Just a guess. Might be a signtool issue. Try the signtool from C:\Program Files (x86)\Windows Kits\10\bin\<Your architecture>\signtool.exe and C:\Program Files (x86)\Microsoft SDKs\ClickOnce\SignTool\signtool.exe .

It is not a signtool problem. .appx file seems to be damaged, I can't open it with a double click:

An error occurred while parsing the application package.

I am also unable to run a UWP Exported appx. I tried removing all versions of my custom certificate then recreating it using the SDK of my current version of Windows (10.0.18362.0).

I get the same error with the signtool:

"C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\x64\SignTool" sign /fd SHA256 /a /f godotCapabilitiesTest.pfx /p "###actual content removed###" godotCapabilitiesTest.appx
Done Adding Additional Store
SignTool Error: This file format cannot be signed because it is not recognized.
SignTool Error: An error occurred while attempting to sign: godotCapabilitiesTest.appx

Number of errors: 1

It does appear that the appx generated by is invalid:

Unfortunately I can confirm the bug. Tried with several versions of the signtool.

It seems to be a bug in the way Godot packages the UWP-file. I was able to get it signed after unpacking the appx-file and then repacking it:

.\makeappx.exe pack /d C:\path\to\folder\ /p C:\path\to\folder\mygame.appx

The following appx can be installed without a problem. However the game crashes instantly upon start, so there still seem to be generall problems with the UWP exporter.

Fantastic news. Thanks @GeorgeS2019 .
I'll be keeping an eye out for it to do confirmation testing.

[GeorgeS2019]
