I have added a chart, but it seems it just loading forever and so I would like to delete it and try again.
However, I can never get into the Properties manual, nor I can right click on the chart to delete it.
I had also tried to use the "Delete" button at the bottom, but still it doesn't respond.
Therefore, I had tried to Load the app without data, and then Right click the sheet to Edit.
Then, it just returns me an error -128 as shown below. Is this a bug?
Or most importantly, how can I delete the chart and allow me continue editing?
