This was a major failure of Apple software engineering test and release procedures. (The last time I introduced such a serious bug into released software was 1985.) I use EOS Utility 3 to update date/time and IPTC info on my camera and I am unhappy about this loss of functionality.
After upgrade to macOS 13 Ventura, both Android File Transfer and EOS Utility 3 stopped working on my iMac. The USB ports were set to power only and no data during the update.
Someone at Apple support suggested that I reset NVRAM on my iMac and that restored data functionality of the USB ports. After that, Android File Transfer works and the Apple Image Capture App can talk to my EOS R5 over the USB C cable that came with the camera. EOS Utility 3 still does not work. This demonstrates that the USB firmware in the camera is fine, but EOS Utility 3 still has a problem. If resetting the NVRAM is necessary, that should have been noted by Apple software engineering and put into the release notes or better yet put into the software that did the update.
I have not yet tried deleting and reinstalling EOS Utility 3, so it is possible that might work.

This is my best guess for the origin of the bug:

Accessory Security
New Features
On portable Mac computers with Apple silicon, new USB and Thunderbolt accessories require user approval before the accessory can communicate with macOS for connections wired directly to the USB-C port. This doesn’t apply to power adapters, standalone displays, or connections to an approved hub. Devices can still charge if you choose Don’t Allow.
You can change the security configuration in System Settings > Security and Privacy > Security. The initial configuration is Ask for new accessories. Configuring an accessibility Switch Control sets the policy to always allow accessory use. Approved devices can connect to a locked Mac for up to three days.
Accessories attached during software update from prior versions of macOS are allowed automatically. New accessories attached prior to rebooting the Mac might enumerate and function, but won’t be remembered until connected to an unlocked Mac and explicitly approved. (43338666)

While my iMac has an Intel CPU and not an Apple CPU, I speculate that Apple software engineering failed to perform adequate testing on machines with the Intel CPU before releasing the update.
