Yes. This is a problem with a 'clean' installation of Gimp 2.10.4 in Windows.
A comparison of the Gimp 2/bin folders 2.10.2 contains libenchant.dll while 2.10.4 contains libenchant-2.dll
Installing 2.10.4 over 2.10.2 provides the file.
or
If you have a trusted source you can add the file libenchant.dll yourself.
More than a good bet that there will be a new Windows Gimp 2.10.4 installer before long
