It’s working fine on Windows 11 here.
A couple of versions back I experienced issues with an upgrade refusing to launch. I uninstalled darktable, renamed its original installation folder, then re-installed. This worked for me and it picked up on my previous preferences from AppData. It might be worth a try.
Alternatively, this portable version as provided by Dave Goldberg will serve as a stop-gap. Just unzip it and launch the program via run_dt.bat
