Whew, Catalina certainly has it's share of problems * the new hardware seems suspect too.

Have seen Brand new Macs need a Reinstall of the OS. :(

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck.

Hi. I had the same issue with four Apple Macbook Pro 13 inch laptops (2016). I followed all the same troubleshooting steps, with no success as you discovered. The problems started in March after updating to Mac OS 10.15.4 "Catalina". In 2 cases the FaceTime cameras were disabled, and would not start, and in another 2 cases the cameras would attempt to start, but then they would shut down. After a lot of discussion with Apple Enterprise Support, they could not find a solution, and they agreed to replaced the main logic boards and the cameras (which includes the whole screen and lid). Problems solved, but a very expensive proposition to fix 4 laptops. I have 120 of the same model in my school, and I anticipate more failures as we roll out "Catalina".

I hope this helps somebody.

I don't see anything wrong, however you are not backing up the computer. At the very lease you need to begin using Time Machine or you will lose your data. Please purchase a external HD (recommend a 2-4 TB model) like a https://eshop.macsales.com/shop/owc-mercury-elite-pro and then begin using Time Machine. By ignoring backing up your computer this is a guarantee you lose data including photos, music, important financial information, movies, and other data files not to mention applications you may have paid for.

As for your problem with the FaceTime Camera, please give AppleCare a call, if you do not know their phone number please use AppleCare contact Information

Rerun the report a few times & see if that Serial# changes like after a restart, should look like this...

FaceTime HD Camera (Built-in):

 Product ID: 0x850b

 Vendor ID: 0x05ac (Apple Inc.)

 Version: 7.55

 Serial Number: CC2C5302QRDGGDLP

 Speed: Up to 480 Mb/sec

 Manufacturer: Apple Inc.

 Location ID: 0xfa200000 / 2

 Current Available (mA): 500

 Current Required (mA): 500

 Extra Operating Current (mA): 0

 Built-In: Yes

Are your USB ports working, Camera us on USB bus.

Have you checked the privacy settings and the parental controls?

From that Serial# I'd say you have bad RAM or corrupted Drive or OS... or maybe the Camera is shot???

My problem is the same as the above with the Camera but on restart it will work until the next time that I want to use Skype or FaceTime. I will go to restart my iMac and it will work again! Obviously a software issue with Catalina. My iMacwas bought new in March 2020. Can anyone please help?

Are you creating a bootable clone of your drive or are you manually copying files to this backup. If you are doing things manually you really do NOT have a backup protocol.
