FrameMaker crashes when opening certain translated MIF files generated by Lara Translate

Hello,

I'm experiencing an issue with translated MIF files and I'm trying to determine whether the problem is related to FrameMaker, the MIF format, or the translation process itself.

Environment

• Source files: MIF files generated from a FrameMaker book
• Translation platform: Lara Translate
• Output: Translated MIF files
• FrameMaker version: 2026 (18.0.0.206)

Issue

I upload multiple MIF files to Lara Translate for translation. Most translated files open correctly in FrameMaker, but certain translated chapters consistently cause FrameMaker to crash when I attempt to open them.

What's interesting is that:

• The issue only affects specific chapters.
• The same chapters fail repeatedly, even after being translated again.
• Other chapters from the same project open without any issues.
• The problem occurs across different target languages.
• Re-translating the affected files produces the same result.

Troubleshooting Performed

1. Uploaded the original MIF files again and requested a new translation.
2. Compared successful and unsuccessful files at a high level.
3. Tested multiple languages.
4. Verified that the same chapters consistently fail while others succeed.

Observations

Because the failure is reproducible with the same source chapters, regardless of the translation attempt, I suspect one of the following:

• Certain MIF structures in those chapters may be causing corruption during translation.
• Specific translated strings or special characters may be breaking the MIF syntax.
• The translated MIF files may contain invalid MIF markup that causes FrameMaker to crash during parsing.

Questions

• Has anyone experienced FrameMaker crashes with translated MIF files generated by external translation platforms?
• Are there known MIF elements that are particularly vulnerable to corruption during machine translation?
• Is there a recommended method or tool for validating MIF file syntax before opening the file in FrameMaker?
• Are there FrameMaker logs, crash logs, or validation tools that could help identify the exact location of corruption within a MIF file?

Any suggestions would be greatly appreciated.

Thank you.
