There could be some kind of error going on in the Unreal scene. The error is probably related to your Unreal project settings. This can happen even if you have nothing added to your scene.
You could check for Unreal errors in the Unreal Engine Log:

Or check the output log in Unreal Editor by running the project in Live Sync: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/obtaining-graphics-and-virtual-assets/creating-content/creating-content-for-aximmetry-de/ue5-how-to-install-and-work-with-the-unreal-engine-based-de-edition/#interactive-editing

Warmest regards,
