Error synchronization Windows desktop client with a network drive


we use the desktop client and would like to synchronize the data as virtual files.
The following problem occurs with the Nextcloud Windows Desktop Client in use with a mapped network drive:

If a network drive “e.g. H:\Nexcloud” is specified as the target path, a few files will be synchronized before the synchronization aborts with the following error message:
“The file could not be updated. Couldn’t convert to placeholder.”
If the synchronization is started again, a few files will be synchronized again before the error mentioned occurs again.

If the files are synchronized to a local drive (e.g. C:\Nextloud"), this works without errors.
Are network drives not supported by the desktop client?

Version Nextcloud Desktop Client: 3.12.0
Windows version: Windows 11 22H2

Nobody any idea?
