Problems with overheating of the HERO8 (and other GoPro cameras) are well documented, along with some workarounds and mitigation strategies. But it's hard to know how "close to the edge" one is operating. Using Telemetry Extractor (https://goprotelemetryextractor.com/free/#) you can extract the temperature trajectory from a recorded video. After loading a .mp4 file for analysis by Telemetry Extractor, click on Accelerometer, then CSV to export a .csv file. In addition to accelerometer data, the file contains temperature data, which allows you to examine the trajectory of the device temperature.
Using this facility I have found that my HERO8 Black seems to shut down when the device temperature reaches about 77.8 degrees C (~172 degrees F). (Any manufacturer representative with the actual specification is invited to supply it here). Of course one cannot monitor temperature in real time this way, but with experience one can get a sense of which environments and settings are most likely to approach the limit, and possibly cause the camera to shut down.
