Impossible to delete an item categorie

[Azrod]

Hi, I'm trying to delete an Item categorie from a copied version of the demo database but I get this error whenever I try :

OutOfMemoryException: Out of memory
System.Collections.Generic.List`1[T].set_Capacity (System.Int32 value) (at <c9d3ffd4b98649ee9989e1908eaca019>:0)
System.Collections.Generic.List`1[T].EnsureCapacity (System.Int32 min) (at <c9d3ffd4b98649ee9989e1908eaca019>:0)
System.Collections.Generic.List`1[T].AddWithResize (T item) (at <c9d3ffd4b98649ee9989e1908eaca019>:0)
System

How can I fix that pls?

It seems you haven't pasted the full error message. Unfortunatly without the full error message we do have enough to go on.
If it happens again, please make you you copy it in full
