Start by inspecting getCurrentAccountId in DataStoreExt.kt:16, then follow its use through AccountSettings.kt:80 and MainActivity.kt. Test a clean installation on Android 9 if possible and investigate the first-launch path shown in the stack trace. Done means the app no longer crashes when opened for the first time after installation.
