Zepto app becomes unavailable after a few launches

The Zepto app cannot consistently be launched from Niagara Launcher. After installing or reinstalling Zepto, it initially works normally for the first 2–3 launches. After that, tapping the Zepto icon in Niagara Launcher starts showing “App isn’t available” and the app does not open.

I have reproduced this issue twice by uninstalling and reinstalling Zepto. Each time, the app worked normally for the first few launches and then the same issue returned.

Steps to reproduce:

Install Zepto on the device.

Open Niagara Launcher.

Find the Zepto app in the app list.

Tap the Zepto icon and launch it a few times.

After approximately 2–3 successful launches, tap the Zepto icon again.

Niagara Launcher displays “App isn’t available” and does not launch the app.

Uninstalling and reinstalling Zepto temporarily fixes the issue, but it returns after a few launches.

Expected behavior:

The Zepto app should remain launchable from Niagara Launcher after installation and repeated use.

Actual behavior:

After a few successful launches, Niagara Launcher incorrectly reports “App isn’t available”, even though Zepto is still installed on the device.
