Is the Gimp 2.10.4 the latest from http://www.gimp.org? The setup files is called gimp-2.10.4-setup-1.exe ie rev1 Python tools not starting and could be an earlier Gimp 2.10
As you report it looks like a problem is TWAIN related. Do you get the scanner showing up in File -> Create -> Scanner/Camera
There were earlier reports of TWAIN not working, It is an old 32 bit plugin, no developers there to fix it.
I use linux so no real easy way to check what works in the way of scanners.
Not usually necessary to reinstall Gimp but this case...maybe.
Uninstall Gimp from the uninstall menu.
If anything remaining in C:\Program Files\GIMP 2\... delete it
Rename-to-disable/move any existing Gimp 2.8 user profile
Install Gimp 2.8.10 and it will be a new clean installation.
Your old Gimp 2.8 scripts/plugins still in the old profile - add to the new profile checking that they work
