How to reproduce:
1. Open the “CollisionBugReport.zip“ project
2. Open the “SampleScene”
3. Enter the Play Mode
4. Press the “1” key (for the RedCube to ignore BlueCube collision)
5. Press the “2” key (for the BlueCube to ignore GreenCube collision)
6. Press the “3” key (for the BlueCube to stop ignoring GreenCube collision)
7. Observe the Game view
Expected results: Only the BlueCube and GreenCube Colliders start colliding
Actual results: All Colliders are colliding
Reproducible in: 2023.3.0b7, 6000.0.2f1
Not reproducible in: 2021.3.38f, 2022.3.29f1, 2023.3.0b6
Reproduced on: Windows 11 Pro (23H2)
Not reproduced on: No other environment tested
Note: When the “Physics.IgnoreCollision()“ is triggered on any other Collider but the GreenCube, it will fix the issue (meaning, only the GreenCube collision will not be ignored, and the collision of the Ignored Collider)
