Cannot set tags for .jpg files

[SimonKravis]

Using TagLibSharp 2.3.0 from C# on Windows 11 to set Title metadata for JPG file with code below does not add any metadata
TagLib.File tagFile = TagLib.File.Create(sFile); tagFile.Tag.Title = sTag; tagFile.Save();

File metadata from ExifTool is shown below. A zero size file SetFromImageFails.txt is created in the folder containing the JPG.

I am seeing similar behavior as well. If the metadata on an image is modified manually, it succeeds, but an image with no existing metadata seems to be skipped.

There are no errors when setting the tag or saving the changes.

(The tag output is identical after the 6th line)
