My UR28M hardware does not work with Mac OS Catalina software!

Hello, I had to reinstall my Steinberg hardware that I have been using for a long time. This is due to the Mac version support problem. I installed the software. I introduced my latest UR28M sound card, but although I read all the articles and tried again and again, I cannot see the DSP FX or application mixer. Hardware is not available in Steinberg either. I’m trying to transfer it to a USB license, but it doesn’t work either. My UR28M sound card, which I was able to use before, does not have software.
Macos Catalina 10.15 ver. I have a Cubase 13 studio and my audio recording has stopped. Please
