Problem with my UR22 mkII with guitar on DAW for a week now

Hello, I’ve been having a problem with my UR22 mkII with guitar on DAW for a week now.

I have a Mac Studio M1 Ultra with Tahoe v26.1, and I use Logic Pro v11.2.2. Everything was working fine until a week ago. Since then, when I connect one of my guitars to input 2, with input 2 Hi-Z pressed, if I set the Mix Input/DAW control to DAW, I get no sound, either from Logic Pro or Amplitude. I get very flat sound on this Mix control on Input, but nothing in DAW. I’ve tried pretty much everything. I connected the UR22 directly to the Mac. I installed the latest UR22 driver, “Yamaha Steinberg USB Driver V3.1.7.pkg,” without success. I followed the UR22 driver installation instructions carefully. I selected input 2 in Logic Pro. Input 1 on the UR22 mkII gives me the same result, no sound on DAW (I switched to input 1 in Logic to do this test). I changed the guitar cable, but no luck. I also reduced my Mac’s security with the Startup Security Utility, but that didn’t work either.
I’m turning to you for help. I don’t know what else to do. I want to see if you have any ideas for a solution.

Many thanks for your valuable time,

Daniel (Dany)

If you turn the dial to the DAW side, the DAW (Logic) is responsible for monitoring.
