When I try to run Sage 9.0.10 in my Wordpress 5.5.3 theme and install Yarn and then do "yarn build" or "yarn start" I get this error:
PS C:\xampp\htdocs\patrick.visiegroep\wp-content\themes\visiegroep> yarn build
yarn run v1.22.5
$ webpack --progress --config resources/assets/build/webpack.config.js
Error: No files matching the pattern "C:\xampp\htdocs\patrick.visiegroep\wp-content\themes\visiegroep\resources\assets\**\*.s?(c|a)ss" were found.

PS C:\xampp\htdocs\patrick.visiegroep\wp-content\themes\visiegroep>
With "build" and "start" always I get
Error: No files matching the pattern "C:\xampp\htdocs\patrick.visiegroep\wp-content\themes\visiegroep\resources\assets\**\*.s?(c|a)ss"
and I can't find what went wrong, because it used to work before I had to nuke my whole installment of Wordpress and Sage. After reinstalling this happens.
