I think there is a bug that causes the blender crash.
I test the issue with at least 10 different maps from HDRIheaven and png from various websites and the result was always the same.

Step to reproduce the issue.
1- Select LuxCore as the renderer
2- Select any 16K/bigger HDRI as an environment map
3- Try to change the ENV gamma
First, changing parameters is taken too much time compared to other renderers with the exact same steps.
Second, After a few try blender/3dsmax/LuxCore getting unstable and most likely crashes.
I think the issue is coming from converting all maps in LuxCore and not just use them. (it somehow no other choice with plugins like blender plugin)
It can be reproduced with any other big HDRI, or Png texture, used on objects material or environment map.
