ESP32 runs wild, can not stop or reboot. Gets hot.

[samtal]

I have an ESP32 WROOM dev board that was running my program OK (Arduino esp32).
At a certain point in time, it stopped running my program and got hot. (other esp32 runs the same program OK)
The serial port reads continuously the following at a very high rate, while the 3.3 V chip gets hot (It draws 0.5 Amp!):
(The overheating may be caused by the extreme running program ?);

Serial port COM6 closed

again and again, .... endlessly...

I can not stop it, can not reload the program, and running the esptool I get the message:
"COM6 failed to connect: Failed to connect to Espressif device: Wrong boot mode detected (0x1f)! The chip needs to be in download mode."
I tried the boot button, reset, but nothing stops the running or enable program reload.
Is there a way to hard reset the chip?

Likely the module was subjected to something not good (overvoltage, power spike, static electricity, ...) that fried the flash chip inside the package. The ESP32 is trying to boot from that but fails. Normally the ESP32 itself doesn't get hot in that state; it's more likely that the flash broke in such a way that it developed an internal short and is pulling way more power than expected through the ESP32 VDD_SPI pin, potentially heating up both chips.

Thanks. That makes sense and I therefore decided to give up and abandon the unit.
(I have a 24V component in a closed electrical circuit which may have killed the chip. Added now an optical device in between).
