I just upgraded to v5.2 and I can no longer save changes. I get this error: Could not write to file /Users/if/Documents/GnuCash folder/ gnucash_transactions.gnucash.20181105195638.gnucash. 20211205203910.gnucash. Check that you have permission to write to this file and that there is sufficient space to create it. I have gone back to v4.13.
