Getting Started & Setup

Hi,
I have a serious video memory leak issue that makes the editor unusable. The moment I click on the menu on the top (like File, Edit, Window, etc.) and hover my mouse over any of the options, the engine instanlty starts to leak VRAM so much and so fast it just goes over the dedicated 10GB of my GPU [RTX 3080 10GB] and starts to use shared memory until the app / pc [whichever comes first] crashes.

VIDEO SHOWING THE ISSUE

I don’t know what could be causing the issue as it can randomly appear and disappear. Sometimes I can work for like 5 hours before it comes up, sometimes it doesn’t happen for a few days, and sometimes I can’t work for a whole day because it appears from the start and even restarting the pc wouldn’t help.

Issue appears even on completely empty projects so it’s not project related.

I’ve already tried file verifiaction, reinstalling whole engine, restarting pc and updating GPU drivers.
Issue doesn’t appear anywhere else, every game and app works as intended.
Issue appeared on UE5.4 and now on UE5.5

PC Specs:

Column 1 | Column 2
OS | Windows 11 Pro 23H2 22635.4580
GPU | NVIDIA RTX 3080 10GB [Game Ready Drivers 566.36]
CPU | AMD Ryzen 7 5800x3D
RAM | 32GB DDR4 3000MHz CL16

Please help.
