Avid Artist (AKA Euphonix MC) Color panel losing connection - and the page functions would freeze.
OS X 10.13.6, Resolve 15.3.1.
EuCon 18.3 seemed to be the sweet spot. You may wanna try the latest driver, but it may not work. I had to downgrade to 18.3, and now "lock panel to application" actually works, and the panel doesn't freeze.
