Hey, did you try with EOS Webcam Utility Pro 2.0?
It worked for me after upgrading to Ventura, while previous version stopped working as soon as I upgraded macOS.
I've got TV mode selected on my EOS 250D and with 2.0 it's working fine again. I'm on latest version of Ventura.
There are mixed opinions about this, and perhaps the camera model should be considered, but if you didn't try yet with it, I suggest you to do.
Uninstall previous version first if you are not using 2.0. Download it from Canon US website, selecting macOS 12 on filter (yeah, 12, not 13).
If even so it still fails for you or you already tried with 2.0, I guess you will need to wait for a newer version.
