dupeGuru crashed with WinError 64

My copy of dupeGuru just crashed during a directory compare. Here the full report text:

Application Name: dupeGuru Version: 4.3.1 Python: 3.8.13 Operating System: Windows-10-10.0.26200-SP0

Traceback (most recent call last): File "hscommon\gui\progress_window.py", line 107, in pulse File "core\app.py", line 332, in _job_error File "hscommon\jobprogress\performer.py", line 46, in _async_run File "core\app.py", line 820, in do File "core\scanner.py", line 174, in get_dupe_groups File "core\scanner.py", line 174, in File "pathlib.py", line 1407, in exists File "pathlib.py", line 1198, in stat OSError: [WinError 64] Il nome di rete specificato non è più disponibile: '\\nas613044\Further_MAIN1\recovery_temp\2018-A\ostor\recuva_2506\ver2\o10new_07.gif'

This popped up just before I expected the full result screen. By the way, the shared directory it says is unavailable is fully accessible.

Below the main window screenshot for more details:
