No Back Up After Catalina Upgrade

I updated to the newest patch for Catalina and I can no longer back up to My Book Live. I can see it in Finder but the browser dashboard does not come up. I can see the IP address in my router listing but the IP does not bring up any WD page. When I try to back up I get an error message that the backupbundle is in use. I have reset the MBL. I have reset the router. I cannot delete the old file to start a new one because it says it is in use.

Any assistance is greatly appreciated.

Has anybody got an answer??? Ive got the same problem on my Mac Pro with A My Book Desktop 8TB Externa?. Kinda freaking me out.
