Crash on GraphicsStateCollection::KeywordsFromShaderAndKeywordNames when calling GraphicsStateCollection.GetVariants()

--

-

Reproduction steps:
1. Open the “ASDQWE” project
2. Open the “Assets/Scenes/SampleScene.unity” Scene
3. In the Hierarchy Window, select the “Test“ GameObject
4. In the Inspector Window, click on the "Update collection list" button from the GraphicsVariantsScriptTest Script options menu
5. Observe the Editor

Expected result: No fatal errors occur when calling GraphicsStateCollection::GetVariants()
Actual result: The Editor crashes due to invalid memory allocation size.

Reproducible with: 6000.0.25f1, 6000.1.0a3
Could not test with: 2021.3.45f1, 2022.3.52f1 (The GraphicsStateCollection is not available in this stream)

Reproducible on: MacOS 14.6.1 Intel, Windows 10 (user’s)
Not reproducible on: No other environment tested

Note: A user reported using the same GraphicsStateCollection during each level to load, warmup, trace, and save solves this issue
