Windows UE5.6 → Mac via Git/GitHub - Content Browser Empty

I am working on a group project using GitHub to share Unreal Engine 5.6 Blueprint project between Windows PC (where project was created) and MacBook (M1) teammates.

Problems

  1. Successfully pulled project repo on MacBook
  2. Confirmed Content/dynamic/ contains .uasset + .uexp files
  3. Generated Xcode project files and built successfully in Xcode
  4. Content Browser remains EMPTY when opening .uproject on Mac

What I have tried:

  • Verified on another Windows PC: git pull works and project opens
  • Verified .gitignore is standard UE5 template (attached below)
  • rm -rf Binaries/ Intermediate/ Saved/ DerivedDataCache/
  • Generated Xcode project: GenerateProjectFiles.sh -project=“…”
  • Full Xcode build (MyProjectEditor > My Mac > Build ✓)
  • Content Browser settings: Show Engine/Plugin/Developer Content ALL enabled
  • Right-click Content/: Refresh / Fix Up Redirectors / Validate Assets
  • Window → Developer Tools → Asset Audit → Full scan

Any Unreal/Git experts who can help?
