Reproduction steps:
1. Open the attached project “Piano”
2. Open Build Settings (File > Build Settings)
3. In the Build Settings window make sure that Development Build, Script Debugging and Wait for Managed Debugger are enabled
4. Build and run by pressing the Build And Run button
5. In the Console window select the Editor dropdown menu and select the Player, when a window pops up saying that a debugger can be attached
6. Press OK on the popped up window
7. In the Player move the character to the piano’s keys (to the right)
8. Observe the Console in the Editor

Expected result: overlapspherenonalloc always returns 1
Actual result: overlapspherenonalloc returns 1 or 0

Reproducible with: 2021.3.28f1, 2022.3.5f1, 2023.1.4f1, 2023.2.0a23

Reproducible on: Windows 10

Notes:
In the Play mode, overlapspherenonalloc will always return 1 when near the piano’s keys
In the Player, pressing the Interact button (E on Keyboard) near the piano’s keys will make the character play the piano and shortly stop

Comments from triage:

• Tested on 2023.2.0b1 on Mac and was able to reproduce
• Noticed that in the player build, that there was a periodicity to the output of the logging output to the Player.log where overlapspherenonalloc would return 1, then 5 zeros, and this would repeat (player was positioned in front of the piano in this case. When entering playmode from the Editor, and similarly placed, the log output was consistently 1.
