When a Player loop was blocked by a Modal window function and then the app was unfocused and focused, it started another player loop recursively which caused dead locks in graphics code. Issue is now fixed, the additional player loops are no longer called in this situation.

Steps to reproduce:
1. Open the “ModalDialog” project
2. Build And Run the project
3. Click the white circle
4. Switch to some other window
5. Switch back to the application

Expected result: Can continue interacting with the file dialog
Actual result: The application froze

Reproducible with: 2021.3.16f1
Could not test with: 2020.3.43f1 (throws errors), 2022.2.1f1 (throws errors), 2023.1.0a24 (throws errors)

Reproduced on: macOS Monterey 12.2 (Intel)

Note: The issue is reproducible only in a build and only on macOS
