Research direction
Start with the minimal reproduction at https://codesandbox.io/p/devbox/nrgx28 and reproduce the error by editing a cell in the AAAA column when a group has one child item. Trace the grouped-table editing and regrouping entry points in the TypeScript source. Done means the edit updates the data, produces no console error, and recalculates the group correctly.
