Solution 1Recommended

Restart Your iOS or iPadOS Device

Adobe has released an official fix for this specific iOS/iPadOS crashing issue, which can be applied by simply restarting your device.

This particular bug was acknowledged as a known issue affecting Adobe Acrobat Reader on Apple mobile devices. The development team has since deployed a background fix.

To ensure the application registers the update and clears the faulty temporary memory causing the crash, a complete device restart is required.

Force close the Acrobat app

Swipe up from the bottom edge of your screen and pause in the middle to open the App Switcher. Find the Acrobat Reader preview and swipe up on it to close the app completely.

Restart your iPhone or iPad

Press and hold the volume button and the side/power button simultaneously until the power-off slider appears. Drag the slider, wait 30 seconds for the device to turn off, then press and hold the side button to turn it back on.

Reopen the app

Once your device has restarted, tap the Acrobat Reader icon on your home screen and try accessing your PDF file again.

Official Fix Applied: Restarting your device should permanently resolve this known mobile app crash as it applies the hotfix provided by Adobe.

Frequently Asked Questions

Why does my PDF app crash immediately upon opening?

App crashes immediately after launch are usually caused by corrupted temporary cache data, an outdated app version, or a specific software bug on the developer's end. In this case, Adobe identified a specific bug on iOS/iPadOS that required a backend hotfix.

Will I lose my PDF files if I uninstall and reinstall the app?

If your PDF files are saved only locally within the app's isolated storage folder, uninstalling the app will delete them. Always ensure your documents are backed up to iCloud Drive or an external cloud service before removing any mobile app.

How can I read an urgent PDF if the app won't stop crashing?

You can use the built-in Apple 'Files' app, which natively supports reading standard PDFs. Alternatively, you can download a reliable third-party alternative like WPS Office to view and edit your documents without interruptions.
