Unity 6.2 has reached it's end of life, please upgrade to 6.3.X or onward for versions where this issue has been fixed. Cheers, AlexRvn.

Unity 6.1 is no longer supported, as such this issue will not be handled on this release stream.

How to reproduce:
1. Open the “IN-109119.zip“
2. Open the “SampleScene“
3. Open the Task Manager
4. Enter Play Mode
5. Observe the Task Manager

Expected result: Memory usage is stable and does not increase
Actual result: Memory usage increases fairly fast ( 200MB/min )

Reproducible in: 2023.3.0a5, 6000.0.54f1, 6000.1.13f1, 6000.2.0b11, 6000.3.0a3
Not reproducible in: 2023.3.0a4

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Notes:

Leaving Play Mode releases the memory
The more GameObjects there are with the same “EnableSwitch“ script, the faster the memory builds up
The MeshColliders do not have to be disabled/enabled in the same frame
Reproducible in the Player as well
