The core issue lies in the package name. In standard Android development, package names follow reverse-domain notation (e.g., com.company.game). Your string uses com.nvidia.valvesoftware.halflife2. Notice the missing dot between valvesoftware and halflife2.

It should likely be: com.nvidia.valvesoftware.halflife2 (with a period) — Wait, looking again, your string has no period there either. Let's correct the assumption.

The correct package name for Half-Life 2 on NVIDIA Shield is: com.nvidia.valvesoftware.halflife2

Your malformed string is: com.nvidia.valvesoftware.halflife2 (Notice valvesoftware.halflife2 has a period, but your typed string in the title does not). In fact, re-reading your title: main.22.com.nvidia.valvesoftware.halflife2.obb appears to have valvesoftware.halflife2 concatenated.

This suggests a typo in the error message generated by a custom launcher or a corrupted download script.
