Freeze/Crash on DynamicHeapAllocator::Allocate when Webcam is used in the Editor and in another application at the same time



Reproduction steps:
1. Open the attached “WebCamRepro” project
2. Open the “badwebcam” Scene
3. Enter the Play Mode
4. Open another app that uses Webcam

Expected result: Editor continues to display Webcam Texture in the Play Mode
Actual result: Editor crashes

Reproducible with: 2021.3.29f1, 2022.3.7f1, 2023.1.8f1
Couldn’t test with: 2023.2.0b3 (“Attempting to upload graphics texture in invalid state.” error when entering the Play Mode)

Reproducible on: macOS 13.5 (M1 Max), macOS 13.4.1 (Intel)
Not reproducible on: No other environment tested

2021.3.29f1 crashes after exiting the Play Mode
2022.3.7f1 freezes
Crash on Intel MacOS is inconsistent (only reproduces on some machines)
