Trouble Connecting Canon EOS R5 (Latest firmware 1.9.0) to EOS Utility 3.17.2.1 on latest macOS 13.6

I am having issues connecting my Canon EOS R5 (Latest firmware 1.9.0) to my Mac on latest macOS 13.6 via the EOS Utility 3.17.2.1 (latest)

I have the latest software and have gone through the user manual.

I have uninstalled canon Software and reinstalled without any improvement...

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.

Programs such as Google Drive or cloud storage programs can interfere with the EOS Utility. Also, having Canon's EOS Webcam Utility installed will cause the EOS Utility to fail to connect to the camera.

Greetings,

By chance, do you have wireless or Bluetooth currently enabled on the body?  If so, please disable them as the camera can only communicate over one interface at a time.  

I've read about the new 1.9.0 firmware.  It's currently available for download on the Canon Japan website.  I also heard it's being put on units that have recently received support from Canon.  Just curious, did you download and flash this firmware yourself or has your camera been in for service recently?

I haven't heard any feedback on it yet. It's still too new.

The firmware was offered to me via the "Camera Connect" application on my iPhone.

This is a known and ongoing problem with EOSU and macOS Ventura. Many threads on this topic on the site.

It is true, uninstallation solves the issue.

This worked for me as well. I did not have to uninstall google drive, I simply quit the application, restart EOS utility and everything works fine.

Once I'm done using EOS Utility I can restart Google Drive, OneDrive etc.

I notice with Google Drive there is a feature to ask to store any connected media device data to Google Drive. I believe this interrupts the EOS utility USB channel.

I have been struggling for WEEKS with this issue, using my Canon RP. Usually, only restarting my Mac Studio would resolve the issue momentarily. 
I uninstalled the EOS Webcam Utility (which should be considered a crime that this company charges us to use this useless junk) and immediately I was able to connect to the EOS Utility. 
THANK YOU.

I tried with macOS Sonoma - same error.

Turned off all cloud storage apps - same error.

Deleted 3.17 and installed 3.16 (first version compatible with Ventura) - works OK with 1D X Mark III.
