On my esp32dev board i was using the watchdog as follows and it was working perfectly.

So I am building some projects and I stumbled upon a problem, two days ago platformio stopped detecting my board at first errors were: This port doesn’t exit, but now it’s PermissionError.
More accurately: A serial exception error occurred: Cannot configure port, something went wrong. Original message: PermissionError(13, ‘Odmowa dostępu.’, None, 5)
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection.
