Interesting, looks like somehow the settings now install docker as USER instead of SYSTEM so the executables are not included in your PATH by default. I recently moved between Macs and was caught offguard by this change.
Updated my PATH as mentioned by Zil0, but will probably just change the radio button to SYSTEM since that makes more sense to me.
Also for what it’s worth the “diagnose” tool gave no hint other than to tell me docker wasn’t in my PATH
