Crash on BuildPipeline::WriteGameManagersSerializedFile when the output path is null

How to reproduce:

1. Open the attached "IN-151016_repro" project
2. In the menu bar, select "BugHunt" > "IN-151016 Run WriteGameManagersSerializedFile Repro"
3. Observe the crash

Actual result: The Editor crashes with SIGABRT (exit code -6) and no managed exception is thrown
Expected result: WriteGameManagersSerializedFile rejects the null output path with a catchable managed exception and the Editor keeps running

Reproducible with: 6000.6.0a4 (d203f4c2ae2f), 6000.6.0b10, 6000.7.0a5
Not reproducible with: 6000.0.0f1, 6000.0.82f1, 6000.3.23f1, 6000.5.10f1, 6000.6.0a3

Reproducible on: Ubuntu 24.04 LTS, Ubuntu 26.04 LTS (by user), Windows 10 Pro
Not reproducible on: No other environments tested

Notes:

• The crash is triggered by calling ContentBuildInterface.WriteGameManagersSerializedFile(null, default(WriteManagerParameters)) - a null output path
• Also reproducible in batch mode: Unity -batchmode -nographics -projectPath <project path> -executeMethod BugHunt.Packs.ContentbuildinterfaceWritegamemanagersAttributedRepro.Run -logFile editor.log -quit
