Cubase Pro 11 and Steinberg UR24C

Cubase Pro 11 has worked perfectly for me until today, but suddenly it doesn’t recognize my UR24C audio interface.
All the other programs that use the UR24C (Sound Forge, Youtube, VLC, etc.) work perfectly, only in Cubase STUDIO —> AUDIO CONNECTIONS, it does not appear.

What is it shown at Studio>Studio Setup>Audio System?

Mac? Windows?
Driver version?

I’ve already fixed it.
When you reinstall the UR24C drivers,
in Studio → Studio Settings → Audio System “Yamaha Steinberg USB ASIO” has reappeared
Thank you!
