EOS Utility no longer starts, shows "err11"

[Kuiho]

I am trying to connect my EOS R6 to my MacBook Air, but EOS Utility no longer starts. It used to work fine. The reply I get is "connection target not found, err11." What should I do?

Thanks for joining the conversation, Kuiho!

So that the Community can help you better, we need to know exactly which version of macOS is running on your MacBook Air and whether you've recently updated it. That, and any other details you'd like to give will help the Community better understand your issue!

Its macOS Sequioa 15.1. I updated it a minute ago, but it didn't help. The camera says pairing (connection) is in progress, but I'm unable to start EOS Utility.
