That version works fine here. Attach the full output as a file to this report and also see if loading factory defaults works by running blender_factory_startup.cmd

Are you on windows 11? I will test it out, something must have changed in the last two days because the working version is from the 18th.

The factory startup does not crash. I attached the full log in the first post.

Yes, I'm on win11. Your crash is coming from sverchok and typically we ask that things like this are reported to them but this may have exposed a problem in blender.

Let me check with the Node folks first, especially since you indicated this worked just yesterday, as most likely the bNodeTreeInterface.runtime struct is null.

Yes, but the addon itself has not been updated, Blender versions days apart seems to behave differently with addon loading.

@kursadk hi, did a quick search for downloading the add-on. Am I looking at the correct sverchok addon repo: https://github.com/nortikin/sverchok?tab=readme-ov-file#installation?

@PratikPB2123 Try this one branch https://github.com/nortikin/sverchok/tree/bgl_replacement?tab=readme-ov-file

Indeed, can confirm the crash. I'll do the bisect at least.

@PratikPB2123 Thanks, I appreciate it. My point was that the addon did not change or got updated for quite some time, but Blender has started crashing with the last two builds (Feb 19th and the 20th, all the rest of the builds before those dates work fine with the addon). So either there is a breaking API change or there is some unintentional bug there.

The thing is that no addon should be able to do hard crash like this. It is not like this is the X addon does not work with Blender argument. In fact the addon does not even get a chance to cause issues or act broken in Blender, given Blender just shuts down as soon as it starts.

Thanks
