Attempt to access "3D Scene" repeatedly crashes viewer!

[zoldos]

I'm running the latest release of the viewer (clean install). It loads up and logs on perfectly. However, all attempts at using "3D Scene" result in the viewer's crash. I'm on Windows 10 64 bit and an Nvidia Geforce GTX 960 graphics with 4GB vram and 32GB system ram.

Same. Systematic crash on 3D scene. with the exact same GPU and VRAM. Except i'm on Arch linux with LTS kernel and not windows.

I have seen that too on my system over the years... I will get 1 3D view (Scene or object) for sure... but beyond that, each one I open is more likely to crash Radegast, and usually needs to reboot the computer before it will work again.
Windows 10 Pro, with latest updated
AMD AM4 3600X, ASUS Crosshair VIII Hero Wifi MB, 32 GB 3200 MHz RAM, Asus TUF Gaming GeForce RTX 3080 Ti (Also had it before I upgraded, on a GeForce GTX 1080 FTW2)

I see the cause in ~/AppData/Roaming/Radegast/Radegast.log:

14:43:17 [ERROR] - Crash of the 3D scene viewer:

I'm using version RadegastSetup_x86-2.41.357.exe on Windows 11 Pro, with plenty of memory and an NVIDIA GeForce RTX 4070 Ti.
