[ID-4277180]InDesign v21.2.0.030 crashes on quit in SubProcess
Version of Adobe InDesign, InCopy or InDesign Server
Adobe InDesign 2026, Version 21.2.0.30 (Build 21200)
Running on macOS 26.2 (25C56) on Apple Silicon (Mac14,2, 16 GB RAM)
Steps to reproduce the issue
1. Launch Adobe InDesign 2026.
2. Open any document (or create a new blank document).
3. Work normally for a while, or even do nothing.
4. Choose “InDesign > Quit InDesign” or press Cmd+Q.
5. Confirm quitting if prompted.
Expected result
InDesign quits cleanly without any error message and returns to the macOS desktop.
Actual result
• InDesign crashes on quit every time.
• macOS shows a crash dialog stating that “Adobe InDesign 2026 quit unexpectedly” (or similar wording).
• The macOS crash report shows:
• Exception Type: EXC_CRASH (SIGABRT)
• Termination Reason: Namespace SIGNAL, Code 6, “Abort trap: 6”
• Crash is triggered in Thread 10.
• This happens even after:
• Resetting InDesign preferences on launch.
• Deleting InDesign caches and preference folders in the user Library.
• Completely uninstalling and reinstalling InDesign via Creative Cloud.
• Testing in a brand-new macOS user account.
Additional context
• The same InDesign version (21.2.0.30) on my previous Mac and macOS version did not show this problem; the issue started only after migrating to the new Mac (same InDesign version, newer macOS).
• No third‑party plug‑ins are installed (or all third‑party plug‑ins have been removed for testing).
• The crash occurs regardless of which document is open; even a new, empty document triggers the crash on quit.

The InDesign crash report feature is activated, but somehow it isn't triggered. Nevertheless everytime when I quit InDesign macOS shows a crash dialog stating that “Adobe InDesign 2026 quit unexpectedly” (or similar wording). I attached the report to this post and will send a video of the crash to the email above.
