"Ran out of memory allocating x bytes with alignment 0" Error when saving-loading

Yes my Communicator class is a singleton. I will look into Subsystem interface thanks.

But Communicator class is not a UCLASS and variables it is holding are not UPROPERTY either. Can this be the problem?

I have tried forcing garbage collection to see if GC deletes some objects, but it had no effect on crashes I have experienced.

Doesn’t look like you’re storing UObjects so it should be fine (maybe not best practice, but still fine).

The problem is definitely that assignment operation:

    // Save equipments
    CharDetails.EquippedItems = EquipmentManager->EquippedItems;

Maybe Equipment Manager is null at that point so EquippedItems is trash? No idea, you’re going to have to add some defensive coding (nullptr checks, size checks, etc) and see if anything hits.
