App crash when using List View

Hello everybody..

I developed a simple dictionary app based on a Google spreadsheet.
Recently, while working on the design of the app, the app started crashing each time I enter a letter into the "Search list" text box. The problem occurs in both AI Companion and the fully compiled app on my smartphone.

What might be the matter with it?

Many thanks in advance.
