Steinberg UR44 not working with Catalina

I have searching for a solution but I can’t find it. The problem:
Today I updated my iMac to Catalina. The UR44 can not be found. I removed everything and do a re-install. Then I get te message installation failed. Time after time I tried but the same message come’s back. I looked at security in the prefereces but nothing wrong there. Is there a solution?
Please help
