Bug description

Opened GnuCash for the first time since installing Nextcloud Desktop Client 3.9.0 (Windows) on Windows 10. The GnuCash program was unaffected, but when it created its .LCK file in the Nextcloud sync folder, the desktop client threw an error notification that quickly vanished. File "could not be synced due to an error." I grabbed the debug log and a screenshot. In the meantime, the .LCK file appeared in the nextcloud Files system and there were no errors when closing GnuCash.

Also, the server is throwing "Unknown error while seeking content".

This error message is repeatable and occurred again when I reopened GnuCash.

To make matters worse, simply changing and saving my .gnucash file causes the same error. That means I can't work around this problem by ignoring .LCK files.

I was able to reproduce the same error by simply right-clicking the sync folder in Explorer and creating a new text file. The client threw an error about the new text file before I even finished renaming it.

The only thing I tried that did not cause any error was copying a file from one folder to another using Explorer.

Virtual file support was not enabled.

Here is the relevant client log from the first error:

Steps to reproduce

1. Place a .gnucash file in the sync folder.
2. Open the file with GnuCash. (Last open file automatically loads on start)
3. After the first error clears, trying editing and saving the file.
4. After that error clears, try creating a new text file in the sync folder using Explorer. ...

Workaround

1. Close all open files and clear all errors.
2. Modify nextcloud/config/config.php by adding 'bulkupload.enabled' => false,
3. Exit the Nextcloud Desktop Client
4. After restarting the Desktop Client, there were no more errors.

I don't know what gnucash is, however i experience a similar behavior. With virtual files, each time i create a file within the desktop client, a notif msg appear : activity sync

could not be synced due to an error. Quickly after the msg disappear and the file gets synced Windows 11, 3.9.3, c.nc.c

I have a similar issue with QOwnNotes (which often creates files and renames them).
