DB browser keeps quiting

I’ve been trying to practice independent project called air fare data but DB browser keeps quiting on my Mac.

I’ve already tried most of the instructions but not working yet.
I installed [DB.Browser.for.SQLite-3.12.2 version), tried to import the file both with csv or tsv format. But it keeps showing like below. If anyone could help me out to resolve this issue, it would be very much helpful as I really want to practice on this project.Thank you so much.

Did you ever figure out what the issue was? I have that same version of DB Browser and haven’t come across this.

I wonder if there is a problem w/the data set you’re trying to open(?)
