Same thing happening for me in 5.2.1 (and I think it was happening in 5.2.0 as well) and UEFN 5.3.
BUT
I am working on a laptop and this thing happens only when I have editor on an external monitor. Once I move it to the built-in display everything looks ok while on it.
The monitor is connected via HDMI, but now I’ve also tested second monitor via HDMI and DisplayPort (USB-C) with same results.

I am streaming and the menus are being captured properly - I cannot see them, but viewers (and me on a stream preview) can. So the issue seems to be related to just rendering specifically on a device. This is somewhat confirmed by the fact that I can still interact with the “invisible” menu. I am using OBS (streaming software) preview to be able to see what I’m doing 
MY SETUP
LENOVO Legion 5 15ARH05H
OS Name: Microsoft Windows 10 Home (I know, it hurts it isn’t Pro)
OS Version: 10.0.19045, Build 19045
BIOS Version: LENOVO FSCN26WW, 09/09/2022
CPU: AMD Ryzen 7 4800H
GPU: NVIDIA GeForce RTX 2060 (mobile, ofc)
I have both integrated and discrete GPU turned on - “Hybrid Mode” in Lenovo Vantage, which I think technically means that Optimus is ON. Going to turn this off and see if the issue persists.
