The new HE inbuilt drivers are using the newer, better Matter parsing method. Once you switch to the stock drivers, this new mode remains for any other drivers you may try later. When I have the chance, I will update the ChatGPT drivers to use the new parsing method as well to prevent these exceptions and make them work again after switching between the stock and the community drivers.
Hubitat's new IKEA drivers are fully functional and working very well. I suggest that you stick to them.
Update: ChatGPT driver is now updated to use the newParse:true decoding.
