I managed to add 2 custom fields in checkout and registration with the above code, but they don't show up in the edit account page, now i don't know php so i tried to add:

strcmp( $screen , 'edit-account' ) == 0 ||
add_action( 'lifterlms_user_edit-account', 'save_custom_field_data', 10, 3);

but it's not showing in the edit account page, anybody help?

use "account" instead of "edit-account"
like this
strcmp( $screen , 'account' ) == 0 )
it will help you to see the fields on "edit account " page

In case anyone is facing issues with the update code, remove the last true from within update_post_meta() as in my fork here: https://gist.github.com/actual-saurabh/b5df17a9350cb6a47ac595700ecedb07
