Reproduction steps:

1. Create a new VR template project
2. Switch to Android platform via File → Build Profiles
3. Find ShaderGraph package in Package Manager, open Samples tab
4. Import “Production Ready Shaders”
5. Observe the result in the Console

Expected result: Samples are imported successfully, without errors
Actual result: Samples are imported with an error “Failed to update package sample cache. Malformed package version string: Common”

Reproducible in: 6000.0.5f1, 6000.0.45f1, 6000.1.0b3, 6000.1.0b13
Not reproducible in: 2022.3.33f1 2022.3.61f1, 6000.2.0a8
Could not test with: 2022.1.0a1, 2022.3.32f1, 6000.0.4f1(“Production Ready Shaders" sample not available)
Fixed in: 6000.2.0a1

Reproducible on: Windows 11
Not reproducible on: No other environments tested

Notes:

* The Project Validation tab in Project Settings contains additional errors that persist unless samples are removed. Clicking "Fix" or "Fix All" does not make errors disappear
* In 6000.0 stream, sample is not available in 6000.0.4f1 and is first became available in 6000.0.5f1, even though both versions use the same ShadeGraph package version. Issue starts to reproduce in 6000.0.5f1
