After packing everything turns out white

I completed my game project, configured it for shipping, built then I encountered that problem which is I never able to handle. tried thousand of things (like changing folder, starting new project and migrating or deleting swarm’s saved folder, re-checking engine version and many things that I couldn’t remember but it main “white screen” problem is still consistent.)
What can I do for that, I couldn’t figure out what cause that problem. I attached related images below. please help me.

packed game(exe) looks like that:


In editor game looks like that there’s no problem in editor works perfect:

Windows packaging settings:

Rendering settings:

Engine version: 5.1

I would try disabling post process volumes and turning off all the post process settings just to see if any of them could be the issue.
But, you said you “tried everything” and those are the most obvious offenders, so you might have already done all of that.

Thanks for your reply Detach789, I tried to delete visual effects like post processing, exponential fog even niagaras it continued to being white. my hopes extingueshed, so tired. I will abandon everything soon.

Okay. Try disabling all the lights. It should surely black screen then, right?

If that doesn’t get it to at least not be white, you could try making an entirely new level and copy/pasting all your actors into it. (Sometimes copy/pasting things fixes issues even when duplicating doesn’t.)

My game looked exactly the same when packaging. I was finally able to get it back to normal by changing settings on the directional light. I just changed the lighting to red, saved, packaged it and it was fixed. I changed it back to white and it is still fixed now. Definitely feels like a bug.

Edit: never mind maybe it wasn’t the settings change for the directional light… its broken again

Im having the same problem and it seems to be caused by te reflection probe. I cant fix it, but when the reflection probe gets deleted the white screen dissapears

It looks like it was the reflection probe! I didn’t realize I had one. Thank you!

Where is this reflection probe setting at
