Working temperature and WiFi transmission

Hi,
Does the ESP32-WROOM-32UE has a kind of thermal shutdown for the Wifi transmission ?
It seems that if ambient temperature is greater than 85 °C it stops the Wifi transmission, until it reachs (more or less) 25 °C ambient temperature.
Does it has a kind of thermal protection ?
Thanks

Do you specifically have the high-temperature version of that chip? The 'normal' version is only specified up till 85C. (Also, what do you mean with 'stops the wifi transmission'? What does the software do at that point?)

It seems that the module itself stops the Wifi transmission, until it cool down itself.
Could it be ?

I do not have any logs, I'm actually wondering if there is this kind of themperature protection on the ESP32 ?

No, there is not, hence us asking for the logs
