OS: 15.3.1 (24D70) Blender version: 4.4 LuxCore version: 2.9a1post14
Hi,
I already had this report on Discord this morning. Blender 4.4 had new API changes that are not yet accounted for.
At the moment, our work to re-publish (Blend)LuxCore focuses on 4.2 as the current LTS version. 4.3 seems to work fine as far as I can observe. 4.4 was not tested at all until today.
For testing, I created a hotfix this morning if you want to try it out on 4.4 and give additional feedback: https://github.com/CodeFHD/BlendLuxCore/releases/tag/latest
Just a heads up, there are further errors regarding the UI like
if tool_settings.snap_node_element != 'GRID': ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ AttributeError: 'ToolSettings' object has no attribute 'snap_node_element'. Did you mean: 'snap_anim_element'?
or when closing Blender. But at least on Windows and Linux this fix allows to start rendering.
The warning about bgl I generally know, though not seen it lately, might be Mac-specific. Would be helpful to know if you experience further issues with the version I linked above.
Some additional info for further reports: The version "2.9a1post14" is the version of the LuxCore binary. If all goes to plan, it will be closely tied to the version of BlendLuxCore, but always best to give information which release of BlendLuxCore you installed (in this case: "2.9a4" or "Latest"). I might update the Bug report issue template to reflect this.
Still doesn't render..

The two issues mentioned before have since been included and are available in the rlease 2.10.0-rc.1
We still don't officially target Blender 4.4 with this version, however, primary goal was Blender 4.2 as it is an LTS version, so residual issues may exist. Likewise, testing on Mac, as you already know.
I'll leave this open until the final release of BlendLuxCore v2.10.0 for additional feedback - if you personally want to test with 4.4 again.
Closing as per my last comment, v2.10.0 has been released.
There are other open Issues tracking the continuing problem of crashes on the macOS platform.
