Game Will Not Launch if PublishSingleFile is Enabled

[MeharDT]

Release Type: Official Release

Version: 4.2.0.2122

Platform(s): Windows

Describe the bug If <PublishSingleFile>true</PublishSingleFile> or "Produce single file" is enabled when creating a build, the resulting executable will fail to launch.

To Reproduce Steps to reproduce the behavior:

1. Start Stride 4.2.0.2122 and create a New Game project for Windows
2. Once loaded, open Visual Studio and Publish the project to a local folder
3. Ensure File publish options -> Produce single file is selected in Profile settings

Expected behavior Game should launch when the executable is opened.

Can confirm this seems to have been an issue since 4.1, I have tried before.

Just tested in Master and seems like this works mostly as expected.

Above is compared to the 82 files that get generated without singlefile.

I dont know what the expectation was but this is definitely a lot better.

Can this be closed? Did #2225 fix the issue?

It's not included in a stable release yet but I think we have enough tests on source to consider it solved, I'll go ahead and close.
