Hi there!
Thank you for providing so many details regarding your setup, repro steps and use case. This helps a ton!
In order to better determine the issue, could you send the full log of the run attempt as well as any callstacks/minidumps you can provide? As you’re running in a Development build, there may be more information there.
A few ideas do come to mind however:
- It’s possible your anti-virus/firewall is quarantining some files. Try a re-package and running with it disabled.
- If this is a launcher build of Unreal Engine, try adding bOverrideBuildEnvironment = true; to the target.cs file
- Ensure the “Windows Movie Player” plugin is disabled. This shouldn’t be the cause of the run error, but it can stop a container image from running.
- Try running the -Cmd.exe in the \Binaries\Win64 directory of the packaged project. This will be the one you need to run in the container.
If you try the 4 things above, make sure to re-package!
Let me know how it goes,
Kind regards,
Michael
