When you say "window option" you mean the full Window>Eleven Rack GUI window (not just the Eleven Rack bits of the edit Window top strip?).

Remove all other USB peripherals you can, reboot the computer, try different USB cables, try different USB ports

Do an uninstall of Pro Tools and reinstall. Never use that ER updater installer again.

Can you use your internal PC audio as the Playback engine. If so you should not even need to install the Eleven Rack driver for the ER GUI window to work (well if things work the same as on a Mac). Try that if you can.

Does the Windows device manager show any problems with any USB related devices?

If nothing else works grab a spare hard drive and do a clean Windows install. Install a bare minimum of any drivers (esp. avoid any other USB drivers) or third party software you need then install PT and see if this works.
