difference 57,538.
I took a look at this website. You can compare the 2016 vote percentage to the 2020 vote percentage county by county. It shows Youngkin doing much better than 2016 in all counties except for one. In 2016 Trump won Frederick county by 28%. In 2020, it shows McAuliffe winning it by 39%. That has to be a typo, or them switching the vote. If they’ve switched the vote, Youngkin will pick up a big chunk when they fix it.
