Glad it's OK for you now.
Re. USB connection issue in Windows, I have no idea and experience as I'm using Linux Ubuntu. Normally, some other software (virus, other communications SW, etc.) interferes with the operation of the port, which is required to be dedicated to the Arduino IDE.
For RP2040, in Linux, you have to run post_install.sh after the core installation.
While for Portenta_H7, in Windows, you have to run post_install.bat. But I don't know why there is no need for RP2040.
Anyway, I don't have Windows system to check, and it's better you post a separate issue to ask for help, if still necessary.
Good Luck,
