Restart Your Mac and Update Adobe Acrobat
Applying the latest software patches and refreshing the system memory is the most effective way to resolve sudden application crashes on macOS.
Software updates often include patches for known bugs and memory leaks that can cause multiple document windows to fail. Ensuring Acrobat is fully updated for your specific macOS version usually resolves compatibility problems.
Click the Apple menu in the top-left corner of your screen and select 'Restart' to clear temporary system memory.
Launch Adobe Acrobat (using just one PDF for now). Go to the top menu bar, click on 'Help', and select 'Check for Updates'.
If an update is available, follow the on-screen prompts to download and install it. Once installed, restart your Mac again and attempt to open two PDFs to verify the fix.

Perform macOS System Troubleshooting
If updating Acrobat does not resolve the issue, check for deeper macOS system errors or corrupted preferences.
