I don't know if this is somehow related with LinkStage3 branch or not, here is the most recent traceback output before the crash:

The last thing I was doing is as follows:

I changed some dimensions via Spreadsheet. Then went back in the history, then the crash happened.

I did find something potentially wrong in TaskAttacher onSelectionChanged(), not sure if it is related.

Should be fixed in LinkStage3

Since I can not provide a reproduction procedure, I'm going to close this issue without being able to confirm.
