Trouble Connecting EOS R8 to EOS Utility on a Mac

I am having issues connecting my R8 to my Mac via the EOS Utility. I have the latest software and have gone through the user manual. The message I keep getting is:

"Communication with the camera via USB cannot be established.
Start EOS Utility after closing all the apps that communicate with the camera, and then turn on the camera again."

I am unaware of any apps that I have that would be trying to communicate with my camera in the background. Anyone know what's going on? Thanks in advance.

I was surprised to figure out that even having Preview open with a PDF was interfering with using EOS Utility.
