How to reproduce:
1. Open the attached "IN-115604" project
2. Open the “SampleScene” scene
3. Build and run the Player (File > Build and Run)
4. Use the drop-down to change to a window resolution which is not the native resolution of the monitor
5. Click the "Freeze" button and start clicking anywhere in the Player window until Unity becomes unresponsive
6. Wait until Unity responds again
7. Observe the result

Expected result: Resolution stays the same
Actual result: Resolution changes back to native monitor resolution

Reproducible with: 2023.1.0a1, 6000.0.58f1, 6000.2.6f1, 6000.3.0b2

Reproducible on: Windows 11 Pro (24H2)
Not reproducible on: macOS 15.3 (M2 Ultra)

Notes:
- You can also change the resolution of the Player inside the project settings (Edit > Project Settings > Player > Resolution and Presentation)
- Bug is only reproducible in Fullscreen
- Bug breaks build, launching again or even rebuilding starts the Player in the native resolution of the monitor, to fix this you have to change the resolution of the build manually again
