Hi all,

Twinmotion 2025.1.1 is becoming unusable on my setup. The app crashes randomly—sometimes the moment I click any button, other times after a few minutes of light work. In the last 30 minutes alone it has quit three times, always showing the same low-level thread-stall stack trace:

What I’ve already tried (with zero success)

  1. Deleted ~/Documents/Twinmotion 2025/Config.
  2. Verified and fully re-installed Twinmotion via Epic Games Launcher.
  3. Started with Shift-launch (no project auto-load) and ⌥-launch → Raster mode only.
  4. Cleared asset & thumbnail caches.
  5. Updated to macOS 15.5, rebooted, tested in High-Power battery mode and on mains.

Same random crashes—no pattern except that they happen whenever I interact with the UI.

System details

Macbook pro 16, M4 Pro, 48Gb ram, 512Gb. High power plan.
