Greetings @ArnabSparkle

I believe that’s indicating that there are corrupted or missing DLL files. I’d suggest reinstalling the Unreal Engine 5.0, restart your computer, and then test again. (It’s specifying the PIEPreviewDeviceProfileSelector.dll if you’d prefer to try to replace/repair the file manually) I hope this helps!
