World Partition Tab causes crash

Hello,

I moved my project from 5.0.3 to 5.1. Everything working as it should, but when im trying to just click on world partition tab, everything freezes. After 1 min i got crash. Someone have idea how to fix that? Crash report below.

@Update
I can play in viewport, i can open that map but can’t go to world partition tab.

I have the same issue. In UE_5.1.1 version (Windows) on a standart Open World map I had big combined in BluePrint Static Meshes and Rect Light Sources. Suddenly after reopening the project my level on the World Partition just stopped opening, causing crashes with same errors in Slate Core as [GalacticQuokka] mentioned. I found out that error was more likely in Engine World Partition Tab. If its enabled, then opening a level causing crash. If its closed, then level opens fast without a crashes.

Update: problem was in unofficial dynamic sky system, whith includes custom sky sphere with enabled flag “Is Spatitally Loaded” in actors properties. Disabling this flag solves this issue.
