FPS drops when rapidly switching weapons in Creative/UEFN

Summary

Rapidly switching between any weapons causes noticeable FPS drops and stuttering in Fortnite Creative and UEFN sessions. The issue occurs even in very simple islands, without Verse scripts or gameplay logic reacting to weapon changes. It affects a lot of weapons and appears to be related to the weapon switching process itself rather than island content.
