No CSS in the themes after installing Local by Flywheel

Hello everybody :slight_smile:
I’ve just installed Local by flywheel, and when I activate the theme twenty nineteen for exemple (or another theme), there is only the HTML and not the CSS (no images, no style etc).
Is there anybody having the same problem?
Thank you very much for your answers!

Could you remove the theme and try reinstalling it? File permissions could be wonky.
Another idea: clear your cache!

Did that help?
