Between the esp32 core 3.3.0 and 2.0.17 the only difference is
nano_nora.serial.disableDTR=true
nano_nora.serial.disableRTS=true
when nano_nora.serial.disableDTR and RTS set to false in the 2.0.17 board.txt I got my communication with the serial monitor back but not on the original COM9 but COM8. No DFU and ESP32 family.
I removed the IDE 1 and 2 package from my PC, restarted and installed it again.
I burned a new bootloader on my Nano.
Nothing helps. Uploading a sketch, no matter which, with 2.0.17 removes the DFU and gives me COM8
uploading with the 3.3.0 core and everything functions as expected.
Uploading with core 2.0.17 on my Macbook Pro. –> Everything OK
Connecting the Nano to my W11 PC –> Com9 back, DFU back Serial monitor back
Uploading the sketch with 2.0.17 and gone COM9 and back COM8 (ESP32 family)
Before uploading I have the same report as below on MacOS Tahoe and W11
