App crash when scroll up and down

Android-10_2026-08-29_120716_logcat.json

Hi, when I build and run the app from commit 64434e6 (Gradle JDK jbr-21) on my Android 10 device and Android 17.0 emulator, the app crashes on both when I scroll up and down the astronaut list.

I attached .logcat file for more details.

Start by building commit 64434e6 with Gradle JDK jbr-21 and reproduce the crash by scrolling the astronaut list up and down on Android 10 or the Android 17.0 emulator. Read the attached Android-10_2026-08-29_120716_logcat.json, focusing on the kotlinx.coroutines.CompletionHandlerException during cancellation; done means the list can be scrolled repeatedly without a crash.
