While in the scheme of things, an indexed color image will prevent the hue-saturation tool opening, it should not cause Gimp to freeze.
Re-installing Gimp over and over is usually futile. You Gimp profile remains untouched and that is often the cause. Try renaming your Gimp profile folder C:\Users\your-name\.gimp-2.8 to maybe C:\Users\your-name\.gimp-2.8-bak to disable it. Restart Gimp and it makes a new default profile. See if hue-saturation works.
The other possibility is the image itself, what size/format, anything unusual?
