Sorry to hear that. Yea, seems that the latest updates have been making things rough. I stopped updates at 1.6.3 and 6.6.4...I've owned my thermal since they first came out (#180) I think. I've never had an issue yet luckily. I haven't even been prompted for battery updates. I think that was in 1.6.4 and above
Parrot should be very helpful with you since this has been a well documented issue. You may also find more helpful information in the regular "Anafi" section of this forum. The thermal and regular one use the same web page to post software update information also.
