Dear Jeff
The bug seems specific for Mac built between 2012 and 2013 (iMac, Macbook, Mini) that use HD4000 Intel graphic card. The GPU driver is broken by this update.
Many other users claim to Apple to repair the driver.
Apple told us our Macs are obsolete …despite the problem is not hardware but related with Catalina software, which is supported for these machines.
Apple don’t care seriously at this time. We hope they reconsider.
Some users think that Apple is responsible and have to repair what they broke.

Aha. I have a late 2013 iMac 27" with a NVIDIA GeForce GTX 775M 2 GB graphics card. That probably explains why I’m not affected.
It’s now been 15 days. I used the System Preferences > Time Machine command Add or Remove Backup Disk to remove the Time Capsule and then added it. I said to overwrite the previous backup. The new backup made a lot of progress and then quit. I told Time Machine to Verify the backup and it reported no problems. I told Time Machine to Back Up Now and it got to 56.46 GB of 61.53 GB and then quit.
As I typed this, Time Machine started itself. Interestingly, it said said 56.34 GB of 61.53 GB, then made progress to 56.46 GB (exactly where it stopped before), and stopped. It says Waiting to complete first backup.
Any ideas?
Both Starry Night and Stellarium fail to launch after this update. My MacBook Pro was manufactured in September 2016 and uses the Intel HD Graphics 4000. I purchased it new from Best Buy in November 2016 and is listed as compatible with Catalina. Apple needs to fix what it has broken.
7 weeks later, Apple appears to have fixed the bug in Update 2021-007 with Catalina Security update 2021-008 just introduced today.
After installing Security Update 2021-008, My Stary Night and Stellarium planetarium software launch and run as they did before the 007 update on my MacBook Pro (13-inch, Mid 2012) with Intel HD 4000 Graphics.
