I just see that someone has created a bug report on Exiv2 with exactly this
problem.

The problem can also be reproduced with the CLI tool from Exiv2. Simply setting
a dc.subject tag reduces the size to around 36MB.

exiv2 -M"set Xmp.dc.subject Test" Test.tif

I don't have a github account (the last one I created was shadow banned for
using a VPN or something). 

Maybe you could post there a link to this thread.

The problem is located in libexiv2 shared library. Please report it as a
UPSTREAM bug to the Exiv2 issues pool in github project, attaching the
problematic file and explaining the context.

Thanks for the sample image. Enabling writing of metadata with ExifTool helps,
and it is best to also enable reading.
Exiv2 has a problem with the image:

Exiv2 ( 3 ) :  Directory Image, entry 0x935c has invalid size 38492*1;
skipping entry.

exiftool metadata writing is not enabled (didn't try with it enabled).
Write this information to Metadata - all options checked.

Scan for faces in this image. Name the face and  the 412MB tif file is silently
replaced by a 37MB file.

Have you enabled writing with ExifTool in the digiKam settings under Metadata?
If not, please enable writing with ExifTool and test again.
We urgently need a sample TIFF file with which the problem can be reproduced.
