Confirmed (0fbd3752b3363bb898fd8af68f07e19bee39a347): Changing (ex. by click-drag) multiple properties at once invokes each property's update method in separate threads - thus triggering Blender property setters, while at the same time another update method might have made it to trying to use the property __get__ to get the latest data for the GeoNodes tree.

Line 949 in bl_cache.py is where Blender is trying to load a Blender property, while that same property is simultaneously being written to. With this kind of thing, we'd at best get mangled data when the race condition triggers; it's actually quite nice of Blender to crash for us!

Now that we know what it is, it isn't as bad as we'd thought: Changing one property value at a time should be perfectly safe (barring unfortunate shenanigans). With that said, straight crashes are a bit nasty.

Fix

The fix should be easy enough; just guard the part of __set__ and __get__ using a threading.Lock. See https://docs.python.org/3/library/threading.html#.

It's a good idea to also guard the global caches, to prevent mangled data from making it into caches during race-conditions and causing havoc, even after Blender properties themselves aren't causing crashes.

Lock contention really shouldn't be an issue - this race condition isn't being triggered outside of this kind of special case.

I'm worried the extent may be further. Sometimes GN modifiers randomly stop displaying (associated with a name change?), then this crash happens. Most curious!
