I'm trying to migrate my library from my old MacBook Pro (Mid-2018) running macOS Sequoia to my new MacBook Pro (same OS). But the export keeps failing with the results below:

calibre, version 8.16.2
ERROR: Failed: Failed to export data. Click "Show details" for more information.

Traceback (most recent call last):
File "calibre/gui2/dialogs/exim.py", line 156, in run_action
File "calibre/utils/exim.py", line 213, in export
File "calibre/db/cache.py", line 86, in call_func_with_lock

File "calibre/db/backend.py", line 2729, in backup_fts_database
File "calibre/db/backend.py", line 2721, in _backup_database
apsw.IOError: not an error

Any ideas or advice on how to resolve this? Thanks in advance!
