My ESP32 (in a T-WATCH-2020) doen't connect to either esptool.py or the Espressif ESP32 download tool. In a terminal emulator the following text is repeated at high speed:

How can I regain control of this ESP32 chip?

What error message do you get if you use esptool? From the log you show, it looks like the flash image is corrupted, but that should be fixable by re-flashing it if you can get that to work.
