Tango app crash on Lenovo after redeployment, have to restart device

[bertt]

Sometimes after redeploy the app crashes on the device. current workround is to restart the device and start the app again. Is there a better solution? Whats the cause of this crash?

in Logcat I see error messages about audio/voice.

Maybe related: On crash the voice with message 'Spraakassistentie ingeschakeld' stops halfway

other observation: with my hello world test app this crash after redeploy does not seem to happen. So a minimal reproducible case is welcome.

we did some testing:

• replace deprecated camera with non-deprectated camera
• remove accessibility controls (UAP)
• remove Takohi speech

and crash does not appear anymore

actions:

• buy new version of accessibility controls (https://assetstore.unity.com/packages/tools/gui/ui-accessibility-plugin-uap-87935 UAP)
• replace speech with the default speech

fixed using unity5.5
