Flow Launcher crashes when the computer is not connected to the internet #976
Description
Hi. I have experienced a bug where Flow launcher crashes with the following error message, every time I try to type something into the flow launcher instance when I am not connected to the internet. It crashes for each letter typed. I had done some testing with different plugin settings try to nail down the issue. I think the issue is the web search plugin's search query autocomplete option that causes flow launcher to crash, as it has no source parameter due to the lack of internet connection. Showing the search result as "not connected to the internet" or not showing a result at all would be a good exception. Thank you!
