A bit of a mix here as a check.
The original image edited in a Win10 VM / Gimp 2.10.12 (the latest ...setup-3.exe) but the embedded exif extracted in linux (used ImageMagick for this, and IM not installed in the Win10 VM)
No great difference, obviously there are changes, big files so just the tail here as a comparison. https://i.imgur.com/1amv12j.jpg
The usual with Windows Worked before, not working now, what changed in the interval.
Maybe a bit more information and someone can help. For example, what camera are you using?
edit: Looked at first post again, open camera .jpg in Win10 / Gimp 2.10.12 and immediately export. Exif data all there.
