Updated now can't start my site

Hi! I’ve just updated Local to the latest version, and now when I click to start my site, I get an error that says: ‘Uh-oh! Unable to start site. Error. Error. UNKNOWN: unknown error, unlink \path to redirected folder\AppData\Roaming\Local\run\router\nginx\conf’

Please help. This is the only copy of the new website I am building for work, that I have to present to the board on friday. Thanks!
