 I found the solution! In OneDrive (for business) there is an excel web limit of 30MB (meaning that you can't open the web version above 30MB, because then you need to 'open in excel'). This means that any connection with an excel file in OneDrive via a web link to PowerBI will crash when it is more than 30MB. So I divided my Excel files in multiple files all below 30MB now, and it works perfect!

I just had a similar issue, but it looks like you don't need all your files to be below 30MB, only those that are loaded into the preview (i.e. the first 1000 rows must be contained in files within the size limit).

I solved the issue by downloading a smaller extract of ~6MB and using that as the preview file, but was still able to combine multiple files >40MB in the overall query.
