If you rename any column or filter with a special character like an e-accent "é" the API returns an error online and the report doesn't work.
Test done on latest today versions.
Can you create a simple pbix file with dummy data which reproduces the issue, and share it with us?
You can upload the pbix file to your OneDrive or Dropbox and share the link here.

I made some sample test and it's pretty hard to give you a reproduction because it seems it depends on the data source.
It works with a SQL or Excel file database with the same fields. It doesn't work with a D365 CRM data source.
As the issue related data source and I don't have such environment to reproduce the issue, I would suggest you create a support ticket to get dedicated support.
