Unable to launch app from Applications but can launch from executable

I have created a Mac desktop app (NOT using XCode). After installing the dmg file, the app was installed in the /Applications/Test-1.0.app folder.

When i double clicked the Test-1.0 icon in the Applications folder, the app is not launched.

But I CAN launch the Test-1.0 from the command line:
./Applications/Test-1.0.app/Contents/MacOS/Test-1.0

So the app can be launched directly from the executable but not from the shortcut icon.

My /Applications/Test-1.0.app/Contents/Info.plist looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "...">
<plist version="1.0">

<key>CFBundleDevelopmentRegion</key>

<key>NSHumanReadableCopyright</key>
<string>Company © 2020. All rights reserved.</string>
<key>NSPrincipalClass</key>
<string>NSApplication</string>
</dict>
</plist>

I also unregistered the app from the Launch Services database (lsregister). I tried it again but no luck.

I am using macOS 10.14.6. Has anyone other ideas what might cause this problem? Thanks.
