In the boards manager there is a dropdown with previous versions in it. Find your 'esp32' board manager in the 'all' type, select the version you want from there and the install button right beside it. I have the 1.0.6 board manager and no problems (because I set the baud rate explicitly on both ends and use SWAP OFF) but strange that it does not offer any upgradable version to that.

Installed Arduino 1.8.13, STM32CubeProgrammer and changed the stm32CubeProg.bat on other PC, did all the process to flash the S6v2 again. I was able to do it (Pic attached), but it stills does not work (is not recognized) when i remove the boot jumper.... Im seeing that the stm32 installed in the boards manager is not the 1.4.0 as the wiki shows, now it is 2.0.0 (updated 2-6 days ago) https://github.com/stm32duino/Arduino_Core_STM32 <https://github.com/stm32duino/Arduino_Core_STM32> can that be the problem? does anyone know how to download the 1.4.0??'
