I have Google Play Services installed in a profile.
Pixel Screenshots crashes on launch, with errors like this:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.google.android.apps.pixel.agent/com.google.android.apps.pixel.agent.app.ui.browser.BrowserActivity}
Caused by: java.lang.UnsupportedOperationException: On-device recognition is not available
at android.speech.SpeechRecognizer.createOnDeviceSpeechRecognizer(SpeechRecognizer.java:410)
Installing "speech recognition and synthesis from google" (com.google.android.tts) and "Private Compute Services" (com.google.android.as.oss) from Play Store does not fix this.
So I think it's fair to say anything relying on Private Compute Services won't work.
Pixel Studio spins for a while, then says "We can't verify your device. Please try updating your Pixel."
