Constant Crashing after converting a project to 5.2

Hey,

Started working on a project, was going well and honestly never had crashed before.

I thought id clone it to 5.2 and install some plugins to help with my workflow.
I also thought this would be a good place to test some cleanup and moved some files around and deleted some old folders.

However, without fail I will now get daily crashes only when compiling and often compiling the most arbitrary changes like moving some sockets and renaming them and updating them in their blueprints to match.

This is the constant error I get - the level i’m pretty much always working in is the default FirstPersonTemplate map (I moved some assets around and placed new ones)

But i’ve never used or even tried to use the world partition actor.

Assertion failed: !InActorDesc->ActorPtr.IsValid() || (InActorDesc->ActorPtr == InOldActor) [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Engine\Private\WorldPartition\WorldPartitionActorDescUtils.cpp] [Line: 166]

Here is the rest of the log

I have no idea why this is happened or related - does anyone have any ideas?

I’ve tried backing up my Config, Intermediate and Saved folders but had to restore the initial config folder as its really messed up my lighting settings.

I feel as though removing them helped but it still get the crashes

Hi Nemesi,
have the same problem as you, and I can’t even migrate the map.
Were you able to solve it?

I feel like I must of solved it… cause I don’t worry about crashes anymore

I’m trying to recall what I might have tried to fix this…

Definitely helps to clear any of the Saved/Config/Intermediate folders and having it rebuild…

I think it was resolved by saving my map as an alternate or even copying the map across from the old 5.1 build to the 5.2 build.

Either way the issue is in the maps themselves potentially pointing to old assets.

Try other things like Fixing Redirectors and opening some Blueprints that you see in the test map so that they recompile - it could be they compiled in the wrong order and are broken in very soft ways.
