BUG? pickling error

Open the thread demo file from viewtopic.php?f=4&t=5396&p=19904&hilit=threading#p19904

execute “run_to_launch” and click “Queue work”

do a file save

Error saving storage for /project1:_pickle.PicklingError:Can’t pickle <class ‘_thread.lock’> attribute lookup _thread.lock failed

Wonder if it’s related to the extension pickling errors:

viewtopic.php?f=12&t=6151
viewtopic.php?f=12&t=6147

Any news on this one?

I’ve been experiencing this error as well… It doesn’t seem to actually hurt the file in any way, though.

Still getting this warning in v24000 without adverse behavior, so far.
