Why can't Wordpress find the style.css file?

I have created a theme in blocs for Wordpress. But when I try to upload it to Wordpress, I always get the same error message that the style.css file is not in the folder. But the file is in the folder or zip file that I uploaded. How can I fix this error?

Enclosed you can see the error message


@brechtryckaert could possibly help you here.

Could you dm me the zip file? I’ll gladly take a look.


Sorry, I couldn’t send you the zip file over this forum because I only created my account a short time ago. But I uploaded it into the cloud: https://drive.google.com/file/d/1knD1o5_fJSLmW2tyYm-3A3XCijMcqjvd/view?usp=share_link
Actually I am quite new to Blocs so I just used this tutorial: Building a WordPress theme – Introduction for my wp-page.
Thank you for your help.
