Last week I’ve been busy with updating my project to UE5.2 and initially I got greeted by what looked like a half corrupted world partition map (list of invalid references and all of the assets not in the level.)
After scrambling through the internet for solutions I found that regenerating the visual studios project file solves this issue but only for 1 session, if the editor is restarted the world partition map loses the same object references and is back to being nearly empty.
I tried packaging the build after regenerating the visual studio files but it would then throw the following error:

The blueprint it’s linked to has not been altered since the update and any references to that actor are all valid.
I’ve attempted to Validate all the data in the project but this crashes the editor.
So far have not been able to find any solutions that come close to this issue.
