Packaging error - Crash on running exe file

I converted my prototype from UE4.27 to UE5.0.0 and after fixing a few warning and error messages, I was able to cook and pack IT for development. My problem is the game crashes when I run the exe file with the following crash report message below. The message shows ‘shipping’ even if I run packaging for ‘development’. I would appreciate any advice on this matter. Thank you.

Same problem appeared for me when packaging via launcher, can’t understand why it appeared.
