Yes. Starting up BLUI 0_7_5 ()
On Blender 2.91.2 ()
Instantly closes Blender.
Good to know that it has been moved to a separate plugin.
It is funny actually, I've been checking every week for an update to 2.9 over the last couple months and two days ago I decided to update even without your plugin and lo and behold, there was an update.
I can say with confidence that after having tried to learn Blender a good 5 times over the last 10 years, your plugin helped me get much further than ever before.
It really sucks trying to learn a new software that goes against the conventions of everything you are used to... Now I'm having that same struggle with the Blender Python API, their documentation is... Not great.
