[Genhis][2.0.47] Crash clicking on "show only essential technologies" (TechnologyGraphGui::update)

[Chriom]

Hello,

I'm playing with PyAnodons and some quality of life mods. Some QoL technologies are hidden from the tech tree but can still be found and accessed via FNEI.

When I open the tech tree from one of these hidden technologies (using FNEI), and then click "Show only essential technologies", the game crashes.

ModList :
Full PyModpack : https://mods.factorio.com/mod/pymodpack
VisionRadar : https://mods.factorio.com/mod/VisionRadar
FNEI : https://mods.factorio.com/mod/FNEI

Steps to reproduce:
- Search for Vision Radar in FNEI.
- Click on the dependent technology to open it in the tech tree.
- Click on "show only essential technologies"

Thanks for the report, the crash is fixed for 2.0.48.
