Unreal Engine freezes when saving all

I was working on a 3D main menu, when all of the sudden my unreal started freezing whenever i hit “save all”.
So i created a fresh project and imported only the main menu stuff (a level, 2 blueprints and 5 widget blueprints. Nothing else). I started to do stuff there, but no use. It was still having the same problem after about 10 minutes after working in the project.
Now when i open the project again, modify a single item (for example move one of those starter cubes) and then hit “save all” again. It proceeds to freeze like before).

It doesn’t crash, but it freezes completely and i have to end task in task manager.

Using UE 5.3.2

I had this issue on saving widgets, it turned out if you have a breakpoint on something called from preconstruct in the widget blueprint, it would break on this internally on save and deadlock the entire save process, clearing the breakpoint fixed it.

Thank you! I was experiencing the same problem, and I didn’t have a clue what might be causing it. Deleting the breakpoints in PreConstruct solved the problem.
