beets hanging on import

[mjsmilloy]

Hi, I've been using beets successfully for a while but it has recently started to hang (and needing to be interrupted by the keyboard) ever since I started importing albums in a single directory. This is the message I get after interrupting:

^C^CException ignored in: <module 'threading' from '/Users/mjsm/.pyenv/versions/3.10.0/lib/python3.10/threading.py'>
Traceback (most recent call last):
  File "/Users/XXXX/.pyenv/versions/3.10.0/lib/python3.10/threading.py", line 1538, in _shutdown
    lock.acquire()

All advice/guidance welcomed
