SONOS Binding does not work after update to 3.4.1. anymore

Hello,

after the update to 3.4.1 the SONOS things shows the message “ERROR: HANDLER”. The thing itself says HANDLER_MISSING_ERROR Handler factory not found.

I have already uninstalled the binding and reinstalled - without success.

I had to shutdown and restart my raspi after the update.

I have also tried this several times without success

also cleaning the cache ?
