I’m currently testing my app through live app testing. It was working perfectly fine until the day before yesterday, but since yesterday, I’ve been getting an error during installation after the download finishes when trying to install it on a device.

The error message I’m seeing is: `state:INSTALL_FAILED location:DOWNLOADING_ERROR_FAILED`

I’ve even tried registering an APK file that was previously working with the live test app, and I’m still getting the same error. I’ve also tried changing the version code, but the error persists, and I can’t pinpoint the cause.

Thank you.
