Is there anyway to access or recover iPhoto libraries using 2020 Macbook Pro

You can open them with Photos.app which replaced iPhoto 7 years ago.

Hold down the option (or alt) key and launch Photos. From the resulting menu select 'Choose Library' and point at your iPhoto Library. It will do the rest.

If you prefer not to use Photos there are several 3rd party apps that you can use. Which to choose depends on the kind of photographer you are and your budget.

Unless you are on Ventura.

That no longer works?
