Changes site domain name and lost access to the site

Hello, I have a problem after changing in the dashboard “SITE DOMAIN” name before migrating my local site on live. Unfortunately, after this, I could not view my local site ( after starting flywheel) any longer ( locally). There is an error and it is impossible to see it, and to acess to dashboard, etc… I have changed it again to the previous domain name( which I had before ), it still does not work, impossible to use flywheel to see the site… I am looking for the solution. Could you please help ? Thanking you beforehand.
