Steps to reproduce:
- Create 2 new URP 3D Projects
- In both Select all Feature Sets at the top of the Packages List when the Unity Registry List of the Package Manager is selected
- Install all selected Feature Sets
Actual results: Error is logged and Package installation stalls: " Error adding/removing packages", "One or more dependencies could not be added to the local file system:
com.unity.2d.psdimporter: EPERM: operation not permitted, rename 'D:\Projects\My project (2244)\Library\PackageCache\.tmp-71444-JYuoN5aQyGlt\package' -> 'D:\Projects\My project (2244)\Library\PackageCache\com.unity.2d.psdimporter@bbb90878229a'
com.unity.2d.spriteshape: EPERM: operation not permitted", ..."

Reproducible with versions: 6000.3.15f1, 6000.3.16f1, 6000.4.8f1, 6000.5.0b8, 6000.5.0b9, 6000.6.0a5
Not reproducible with versions: 6000.0.75f1, 6000.3.14f1
Tested on (OS): Windows 11
Notes:
- Issue does not reproduce all of the time, around 2/5 times
- I've had more success in reproduction when installing the Feature Sets with 2 Editors open
- This can also reproduce when creating Templates, indicating this might also affect single Package installations non-deterministically
- Issue might be reproducible on 6.0 as well, not determined
