UR22 MKII disappears after starting Ableton

I’ve used my UR22 MKII for many years without problems, but since a couple of months it does not work with Ableton anymore.

When I connect it to my MacBook Pro it is recognised and it works. But as soon as I start Ableton it disappears from my sound devices in MacOS. In Ableton’s settings I also cannot find it (obviously).

While Ableton is opened I’ve tried to unplug the usb cable and plug it again, but the device won’t show up.
When I close Ableton and plug in the usb cable again it is recognised and works normally until I start Ableton again.

I’ve tried to reinstall the driver, but without success.
I’ve also tried to reinstall Ableton which also didn’t help.
Does anyone know how I can fix it?

Specs:
MacBook Pro with macOS Monterey 12.6.5.
Latest Steinberg driver
Ableton 10.1.43

It’s solved now. Apparently the Steinberg USB driver was not installed properly anymore.
