Yeah, I packaged without Project Launcher (didn’t even know that existed). I get the exact same error as in the thread you mention above. Its especially annoying to pin down if it only crashes ‘sometimes’, but for now I’m still at 5.4 and hope I won’t encounter that bug 
5.5 and 5.5.1 have a critical bug where components on child bps that are placed in a level lose any customized property values in packaged builds. I posted my reply with 100% repro in this thread https://forums.unrealengine.com/t/some-inherited-blueprint-variables-breaks-after-upgrade-to-ue-5-5/2137164/9
Unfortunately this makes 5.5 absolutely unusable for anyone needing to package or ship a game. I’ll try to get a bug report in today but epic needs to fix this ASAP. No legitimate studio can use this version until it’s fixed.

Other weird 5.5.1 bugs involving HISMs:
Hello, I have been trying to install Epic Games for the first time and the installation ends prematurely because of an error. Tech support sent me articles that did not address my problem, my post to different forums have not been published. Any ideas? Windows 11 , 2 terabytes in my C:drive and 4 Terabytes on my D:DRIVE
Thanks
Taking screenshots at runtime (in packaged games) is also broken?
Hahaha, how the hell is 5.5 so broken? Great QA team!!
Has there been any updates on this? It affects Minimap generation, Nav Building & HLOD Generation.
I wrote a bug report weeks ago but nothing…
This is the last time i try a new version of the Unreal Engine… Im waiting a minimum of .2 hotfixes + before we try anything new. This is my fault for trusting these builds were properly QAed since these are issues present even in their sample projects they ship built into the engine…
It’s still broken, we have to wait until the holidays are over. Epic’s offices are closed now…
UE 5.5.1
Bug: (EDIT: not a bug, nanite does not support morphs at the moment)
if nanite is enabled on a skeletal mesh that uses morph targets, the morph targets stop working on game.
Example:
I have a character that blinks and opens mouth when jumping. If i enable nanite with “preserve area” on the skeletal mesh of the character, the character does no longer blink or open mouth when jumping. I tested with other skeletal meshes aswell and nanite broke the morph targets on all tested skeletal meshes.
so, if you use morph targets on a skeletal mesh, you can not use nanite or the morph targets stop working.
This is intended and in their docs its one or the other…

thanks for the info, nanite on skeletalmeshes is new so I did not know morph targets are not supported.
Could you post a link to the mentioned doc so I can read about it?
I found this one, but it does not mention morph targets:
EDIT:
I found it, it is on the same document I linked:
Well, I hope this is supported in the future 
3 weeks without changes in 5.5.2 Github. Will you launch this version soon, but still broken? How long are your holidays?
@Amanda.Schade Please, fix the Fullscreen and/or r.SetRes bugs.
Thank you.
2 days now.
We have to keep complaining and reporting bugs, it’s the only thing to do.
Maybe just create a website… named as ‘unrealbugs.com’ lol… there list of the top 20 bugs and links describing the symtom. Make the website as viral as possible. Maybe the bugs will get fixed faster this way… 
You can already report bugs and track them.

Yep, but I was ignoring ultra-mini changes. In the last 3 weeks there have been a couple of them, which make it looks like if it were received changes more recently.
Absolutely
Unfortunately it’s quite useless, as they usually ignore the reports. 90% of my reports never received a reply, and I usually report actual confirmed bugs. Even with repro projects, to make it faster and easier for them. Almost always ignored (thank you, Epic). I got exhausted and I don’t report bugs thorught that annoying form anymore, unless it’s ultra flagrant, like the Fullscreen bug.

What fullscreen bug?
Can someone help me? Unable to install Epic Games, I had done everything they have asked me to do, I run Windows download trouble shooter but it did not find any errors. It says installation ended prematurely because of an error, I even disable antivirus temporally. Nothing works, brand new computer, Windows 11.
Thanks
This one:
Why would you even need to do that though? It’s 2025, not 2005, just set the resolution scale higher, since it’s going to be downsampled to fit your screen anyways… Want 4k on a 1080p monitor? r.screenpercentage 200 and you’re done. Want 720p on a 1080p monitor? r.screenpercentage 66 and so on.
