Global crash in Premiere Pro (v26.5 / v26.0.2) & AE on macOS 27.2 Beta (Build 26B5086k) when importing media or dragging audio to timeline.
[System Environment]
- OS: macOS Golden Gate 27.2 Developer Beta (Build 26B5086k)
- Application: Premiere Pro (v26.5.1, v26.0.2) & After Effects
[Issue Summary]
Premiere Pro and After Effects crash consistently on macOS 27.2 Beta 3 (Build 26B5086k).
[Steps to Reproduce]
1. Launch Premiere Pro on macOS 27.2 Beta (Build 26B5086k).
2. Drag any audio file or using object mask onto the Timeline / Project panel.
3. Premiere Pro crashes instantly within 1 second (Audio/Media import I/O crash).
4. Launching After Effects fails at startup with "<ae.blitpipe> HardwareBlitpipe" or LocalHub IPC validation deadlock.
[Attempted Troubleshooting]
- Cleared Media Cache and Reset Preferences (Option + Shift).
- Downgraded Premiere Pro to v26.0.2.
- Cleared and locked TeamProjectsLocalHub HTTPStorages cache.
- Launched AE in Safe Mode.
None of the above resolved the issue, confirming a systemic OS API/Metal driver breaking change in macOS 27.2 Beta 3.
