One thing needs to be mentioned is that store won't check the result of your local WACK test. The result of the local WACK test will be affected by the local environment. So that's why it is recommended to test in a new device.
Also, when you upload your app to the store, there will be an online WACK test in the submission certification. Store will only check the result of the online WACK test.

2024-05-10T07:47:27.7666667+00:00 You could make a try about that. If the error shows in a new device, that means the problem will be related to the package.

2024-05-14T06:30:30.0166667+00:00 You could try to check if you have installed the nuget package already using the following powershell command
Get-AppxPackage -Name Microsoft.UI.Xaml.2.* -

2024-05-14T09:26:42.5833333+00:00 Based on the result, you've already installed the package in your device which causes the problem, try to test on a new and clean device.

2024-05-14T09:40:04.5433333+00:00 If you don't have a new device to test and you will need to publish to the store finally, I'd suggest you directly upload your app to the store and wait for the result of the online WACK test.
