Is there any other software that can save the data to the shared folder, or open the shared location?
If yes, please do it for a test.
Please also check whether useing UNC path has the same issue.
From the perspective of Office, it is recommended to add this shared location to a trusted location.
Such as in Word, please go to File > Options > Trust Center > Trust Center Settings > Trust Locations > Add new location.
In addition, please try the steps mentioned in article "An Office program is slow or may stop responding (hang) when you open a file from a network location".
Any updates please let me know.
