Acrobat version 25.x crashes on macOS 26.0.1 when opening PDFs that are stored in shared iCloud Drive folders. The same PDFs open correctly in Preview, Chrome, or when copied to Desktop or to a non shared iCloud folder. The issue happens every time with any file in a shared iCloud folder, so it is fully reproducible.

Environment:

macOS 26.0.1 (25A362)

MacBook Pro M2 Max, 96 GB RAM

Acrobat 25.001.20841 (latest version as of November 2025)

Steps to reproduce:

Save any valid PDF into an iCloud Drive folder that is shared with another Apple ID.

Open that PDF directly from Finder using Acrobat 25.x.

Acrobat launches and immediately crashes.

Expected result:
The PDF should open normally.

Observed result:
Acrobat closes instantly with an EXCBADACCESS (SIGSEGV) crash. The same file works fine if opened from Desktop or a non shared iCloud folder.

This appears to be a regression in the new unified Acrobat app. Acrobat DC 24.x works perfectly on the same system.

Please investigate Acrobat’s handling of shared iCloud Drive folders on macOS 26.
