How to reproduce:
1. Open the attached “IN-147289” project
2. Open Build Profiles window (File > Build Profiles, or press CMD + Shift + B)
3. Select “iOS” custom build profile
4. Switch to the selected profile by clicking Switch Profile button
5. Make sure the Player Settings section is present
6. Build the project 2-5 times
7. Observe the Build Profiles and the Console

Actual result: Some parts of the Build Profiles window disappear and show empty spaces, multiple errors are repeatedly thrown in the Console, build still completes
Expected result: Build Profiles window is unaffected, no errors are thrown and build completes as normal

Reproducible with: 6000.5.0a1, 6000.5.3f1, 6000.6.0b3, 6000.7.0a1
Not reproducible with: 6000.0.79f1, 6000.3.19f1, 6000.4.0a3
Fixed in: 6000.7.0a2

Reproducible on: macOS 26.5.1 (M1 Pro)
Not reproducible on: No other environments tested

Workaround: Selecting a different build profile in list recovers the Build Profiles window

Notes:

If the issue does not reproduce, after 5 builds it is recommended to restart the Editor
After the issue is reproduced, it will no longer reproduce until the Editor is restarted
Appears to only affect iOS profiles
Reproduces regardless whether or not the window is docked
Player Settings must be present for the issue to reproduce, added via “Add Settings” in the build profiles window
Errors thrown: “ObjectDisposedException: SerializedProperty m_PlatformBuildProfile.m_InstallInBuildFolder has disappeared!”; “InvalidOperationException: The operation is not possible when moved past all properties (Next returned false)”
