Google Assistant won't run task when Android Auto is active

I have some tasks written to allow me to do some things "hands free" while I'm driving. They have worked well in the past, but today I noticed that they work only if Android Auto is not running. So if I say, "Run <task name> with Tasker" while AA is not running, Google Assistant will execute it with no problem. But if AA is running, Google responds with "Sorry, I don't understand".

The "Sorry" message is something I understand is expected without AA if the phone screen is off (and that still happens, of course), but I've never before gotten that while AA is running, whether the screen is on or off. Now it does it whenever AA is active. 

Tasker is at version 6.1.29, AA is 9.3.631434, Android 12, Samsung S10e
