App Manifest Validation Error: The attribute 'ShortName' with value '*' failed to parse.

[aredfox]

Description

I am in developer mode on my machine(s) running

• Windows 10 21H2 (19044.2130)
• Visual Studio 2022 17.3.6
• .NET 6.0.402 (commit 6862418796) with win10-x64 and base path c:\Program Files\dotrnet\sdk\6.0.402
• maui-windows 6.0.541/6.0.400 VS 17.3.32929.385

When building a clean MAUI .NET template I get the following error:

DEP0700: Registration of the app failed. [0x80080204] error 0xC00CE16A: App manifest validation error: The app manifest must be valid as per schema: Line 27, Column 144, Reason: Union doesn't support this value.
The attribute 'ShortName' with value 'KodeFoxx.SimpleBroadcast.Presentation.App' failed to parse.	KodeFoxx.SimpleBroadcast.Presentation.App	
```		



### Steps to Reproduce

1. Create File -> New MAUI .NET APP
2. Set to debug, select .net6.0-windows10.0.19041.0 as target to run
3. Press the green button

Expected outcome:
 -> See a .NET MAUI app appear as it comes from the template

Current outcome:
 -> Error on parsing, see below for output. Can't seem to find where to find or fix this file even.
**_The app manifest must be valid as per schema: Line 27, Column 144, Reason: Union doesn't support this value.
The attribute 'ShortName' with value 'KodeFoxx.SimpleBroadcast.Presentation.App' failed to parse._**
