Indesign 2027 Carshing when merging to PDF

According to your crash log posted below (replying here so it doesn’t get buried in hidden reply posts)

Looking through it, the crash is occurring on the main application thread with an EXC_BAD_ACCESS  error, attempting to access memory address  0x0.

What's interesting is the sequence in the crash stack:

AppFramework > CmdUtils::ProcessCommand > DataMergeUI

That points towards InDesign's own Data Merge command processing rather than anything obviously wrong with the CSV or PDF.

Given that you've reproduced this with a completely new document and simple CSV, and everything works correctly in InDesign 2026, I'm leaning towards this being a regression in InDesign 2027.

I also noticed that Monotype Connect (Extensis) has a font auto-activation plug-in loaded. There's nothing in the crashing thread directly implicating it, but it might be worth temporarily disabling that plug-in and testing again, just to eliminate a possible conflict.

(I got an update for Monotype Connect yesterday - maybe you need to update?)

One other thing

Did you manage to test with Data Merge Preview switched off, as suggested?

If it still crashes with Preview disabled and the font plug-in out of the equation, I think there's enough evidence here for Adobe's engineering team to investigate. 

A little update on this scenario….I am now getting crashes at the end of every merge to PDF I do.

The outputted PDF is now correct and is not missing any content, but InDesign itself crashes upon completion.

The files I am using have sensitive information on them so cannot share those, but I can confirm this is happening on any merge to PDF with any InDesign and CSV file I create.

I shall submit the crash log shortly.

Hi ​@Andy_Baz,

Thanks for sharing the detailed information and for testing the issue in both InDesign 2026 and 2027. Sorry for the inconvenience this has caused.

I tried reproducing the crash on my end using a simple document with a single Data Merge field and a CSV file, but I haven't been able to reproduce the issue so far.

Adding to Eugene's suggestion, could you please confirm whether the crash still occurs when Data Merge Preview is disabled before exporting directly to PDF?

Additionally, could you please share the sample INDD file, source CSV, and the PDF generated during the crash, if available? Testing your exact files will help us investigate the behavior further.

Could you also confirm whether the Adobe Crash Reporter appears when InDesign crashes? If it does, please submit the crash report with your email address and a brief description of the issue. You can then share the same email address with me via direct message (DM) so we can help locate the relevant crash logs.

Reference: Adobe — Submit crash reports in InDesign.

You can share the sample files here in the thread or, if they're confidential, send me a downloadable link via DM using Google Drive, Dropbox, OneDrive, or another cloud-sharing platform.

In the meantime, please continue using Create Merged Document, followed by File > Export > Adobe PDF (Print), as a workaround.

Thanks for your patience and cooperation!

How does it look when if you do the merge - but don’t preview? Does it work normally?

Thinking hat on 

The fact that Data Merge previews correctly, Create Merged Document works, and the resulting document exports to PDF without problems suggests that the issue is specific to the direct PDF export process.

A couple of things worth checking:

• Does the same thing happen with a completely new InDesign document containing just one text field linked to a simple CSV?

• If you still have InDesign 2026 installed, does the same file export directly to PDF without crashing?

• Have you tried exporting to a local folder rather than a network or cloud-synced location?

If you can reproduce the crash with a new document and a simple CSV, particularly if it works in InDesign 2026, that would be strong evidence of a regression in version 22.

If it’s truly not working:

I'd recommend reporting it through the InDesign UserVoice bug reporting site, including the crash report and, ideally, a sample INDD and CSV that reproduce the problem.
