Thank you for your reply Casey.
I just noticed that my Zoom required updating so now it is the same version as yours. My WebCam is actually a USB 3.0 WebCam. Logitech BRIO 4k. Have never has an issue before so we'll see if it does it again now that Zoom has been updated.
I have attached a copy of my EFIClone.log. I should have mentioned that I have not changed anything with my CCC including the Shell Script. It has never let me down and I back my system up onto a 500gb Samsung SSD T5. It seems if I'm reading the log file correctly, I cannot open the EFI partition.
p.s. I needed to change the file extension for me to upload it here.
