Fixed in: 2023.1.0a20
Reproduced on: macOS 13.0.1 (Intel), Windows 11 (by reporter)
Notes:
- Above Repro is not reproducible in Builds, but likely duplicates indicate that it does reproduce in Player Builds too
- Adding the Memory Profiler Package (versions 1.1.x+ up to 1.1.0-pre.2) to a repro project and Profiling the Editor will trigger the "Memory" tap UI in the Profiler Window to leak Meshes. Version 1.1.0-pre.2 of the package greatly reduces this effect but can't fix it, because the package's code is not the root cause for the leak (Also see https://issuetracker.unity3d.com/product/unity/issues/guid/PROFB-160).
