Studio issue: The filename components/_latest_posts.scss contains invalid characters

Hi, 

I run into the issue when try to save a file recently. There is no edit since the last successful update.

I also tried empty the file and save but it's still failing with the same message.

I see other people hit the similar issue recently 2 week ago here https://community.lithium.com/t5/Online-Communities/Invalid-SCSS-Error/m-p/432462

However, there is no solution to this yet.

Please advice how to fix this.
