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.

It is a problem that seems to have developed with the 13.4.1 update to Ventura.

I was able to sync my 1D X MkIII prior to that update and now I get that error.

If you are only looking to download images you could get a card reader. If you are wanting the tethering features then we have to wait for Apple to fix the problem.

Turn off the computer. Turn on the camera. Turn on the computer. Boot in safe mode... 🤦🏻‍ All this gymnastics looks way weird. I've just checked on my Mac Mini M1. That bash command works just fine for tethered shooting even with EOS Utility 3 v3.18.0. No fuss, no muss.

I did sort of fix this issue by starting my Mac in safe mode and disabling image capture. The only problem is when shooting tethered I always have to use safe mode.

Have you tried the bash command I mentioned on the previous page? No safe mode is required. Why extra inconveniences?
