I haven't had that issue since upgrading but I cannot use my Google Assistant button now.
That sounds like an unusual bug where the options seems stuck. As much as this might not be the most attractive option, a factory reset should resolve it. If it doesn't, then there might be something wrong with the device or an issue with that specific update in relation to your wireless charger being recognized properly. Have you done a search on your wireless charger recently to see if others are having similar issues?
