Description
Googling "arduino serial oserror esp32s3" shows some number of similar issues.
On my side: windows 11, esp32s3, standard settings, reproducible with blink example.
After successful upload, user receives an error:
Hash of data verified.
Leaving...
Hard resetting with RTC WDT...
A serial exception error occurred: Cannot configure port, something went wrong. Original message: OSError(22, 'A device which does not exist was specified.', None, 433)
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.

After device resets, it reconnects to the OS, but it seems something tries to still use it. Looks like race/someone not being patient. I started to dig a bit.
Current Arduino core, version v3.2.0, uses esptool of version 4.9.dev3, not 4.8.1 as many people seem to think.
This is the version that the tool itself reports during usage in Arduino. It seems to me a version info is not updated per dev releases, but dev releases are used in production.
4.9.dev3 builds as:

A serial exception error occurred: Cannot configure port, something went wrong. Original message: OSError(22, 'Określono nieistniejące urządzenie.', None, 433)

Later, comparing esptool tags, we can see some sleep() here and there:
Especially here: espressif/esptool@v4.9.dev3...v5.0.dev1#diff-cb25ea9381c2f7a537ecf1516335d3a9e8a711a9dbf3d1eff78453a611072103R360
Either way, when I tried the same .bin files with v5.0.dev1, it seems that resets occurs with RTS, and the exception is not raised:

My kind request would be:
- current esptool v5.0.dev1 works for xiao esp32s3 upload well - can we please incorporate it into this arduino core?
- can we use official version of esptool in this core to not confuse people about which esptool version they use?
