2021.11.1 Thermostat Card will not let me save, giving 272 failed message

I just updated to 2021.11.1 today and had installed a Thermostat yesterday that I wanted to add to my frontend however as soon as I choose the Thermostat card it shows my Thermostat but gives an error and won’t let me save the card.

Configuration errors detected:

Anyone else see this before?

Thanks

Update: Turns out there were a number of cards that would error out like entity although entities worked. Also the raw configuration would freeze at a blank empty screen so I pulled down to refresh the app and tried to add the thermostat again and it worked. Everything else is currently working now too so maybe just something corrupt in the app cache?
