Encountered 0x80131500 code while using MSIX Packaging Tool

Hi Guys,

Recently, when I tried to use MSIX Packaging Tool to convert the exe file to MSIX, I got the 0x80131500 error. Checking the log, I got the following part

[2025-07-31 7:14:04 PM] [Debug] MakeAppx : error: Failure at (packageWriter3->AddPayloadFiles( addedFiles, preparedFiles, performanceOptions.memoryLimit)) - 0x8007007b - The filename, directory name, or volume label syntax is incorrect.

So far, it seems that \\?\%UserProfile% is causing the issue. But I am not sure how to solve it. 

The following is the manifest file I used.

<?xml version="1.0" encoding="utf-8"?>

Could someone help me solve this issue? Thanks!
