Hi!
I have a project which previously could be packaged without issue, but now I’m getting a “fatal error” on trying to start the game.
Must mention that I installed the DLSS plugin previously, which caused an error before the game could be even packaged. Had to disable it in order for it to finish packaging at all. I’m wondering if it could still be causing trouble even if I disabled the plugin…
I will post the log from the packaged build.

Hey @Andreas_Bjorshol!
So in the log I’m not seeing any mention of DLSS, so you’re safe there.
There is a failure to launch PixWinPlugin, though. Try disabling that if you’re not using it.
I’ve also seen this exact error code happen with Quixelbridge, and it’s usually solved by a re-installation of that. Give that stuff a shot and get back to us! 
Thank you! I disabled the Pix plugin just in case, no idea what it does so I’m probably not using it. Still getting the same error though.
I have disabled the Quixel plugin and enabled it again, but is there any way to actually re-install it? The Library shows that it’s installed, but gives no option to uninstall it. Do I just delete the Bridge folder in Plugins?
Hey @Andreas_Bjorshol!
You can uninstall Bridge by clicking installed plugins under your desired engine version in your launcher → click remove once open → search for Quixel Bridge in your vault → install to engine.
I hope the above is the solution you need!
Thanks! I will give it a try as soon as I have time.
Just on a side note, I heard that long file paths can cause trouble for packaging as well. I have mine stored in My Documents, but will try to move everything to the root of the drive and see if that might help - if the Quixel plugin wasn’t the problem here.
I have reinstalled the Quixel plugin, and still getting the same error. Will attach the log, in case anyone can make sense of this.

Noticed these two lines mentioning “OptiX denoiser” which is not found:
[2023.03.10-08.35.52:729][ 0]LogWindows: Failed to load ‘…/…/…/Engine/Plugins/Experimental/OptiXDenoise/Source/ThirdParty/OptiXDenoiseBase/lib/OptiXDenoiseBase.dll’ (GetLastError=0)

Okay, for anyone experiencing the same issue and has the OptiX plugin enabled, the solution was just to disable it. I don’t know why this has any effect on a packaged project, isn’t this denoiser for path tracing in the viewport?
