🧩 What this issue looks like
I get an error "...requested the Runtime to terminate..." when working with flashings. Vague error dialog.
The first clue that you have a problem is when you get this rather vague error dialog...
Then when you try to do anything at all, you get this 'Runtime Error!' dialog.
📄 Cause: LineStylesV6.csv has an END line
LineStylesV6.CSV
This is caused by having an 'END' in the line styles text file LineStylesV6.csv.
As a general rule, we have learned that we need an END at the bottom of all CSV files for material definition lists etc, but this one.
✅ NO 'END' AT THE BOTTOM OF THE FILE.
The issue with the END crashing the Flashing dialog is because an ‘END’ had been added to the bottom of the text file LineStylesV6.csv. Once upon a time, you might have gotten away with having that there, but clearly now you can’t have it. This has became apparent in V9.0.
🛠️ Fix: Remove END from the bottom of LineStylesV6.csv
The fix is simple, edit the LineStylesV6.csv file to remove the END.
✅ NO 'END' AT THE BOTTOM OF THE FILE.
🧪 Note
However, having said all this, I cannot reproduce this bug here.
