All bar charts render as a single aggregated bar only for one Google account

All bar charts render as a single aggregated bar only for one Google account. Tables, pie charts, scorecards, and combo charts render correctly. Issue reproduces across browsers, reports, and data sources (Google Sheets and GA4). Other users viewing the same reports see bar charts correctly.

This is happening to me as well. Not only GA4, every single source. Worked perfectly yesterday.

The same thing is happening to me. Stacked bar charts don’t even work anymore. Maybe the AI slope has finally hit Data Studio?
