Acrobat Reader crashes opening LibreOffice user guide

Previously reported at https://bugs.documentfoundation.org/show_bug.cgi?id=172842 where it was confirmed by another user (running Windows 11) but not resolved. I am running Windows 10.

I downloaded the Libre Office user guide and opened it. Acrobat Reader crashed.

I downloaded it again and did a binary compare - both versions were identical, and Acrobat Reader crashes each time.

I open hundreds of PDFs and have never seen Acrobat Reader crash before.

I am using Adobe Acrobat Reader version 2026.001.21691 (64 bit).

I checked for updates and at the time of writing there are none.

I opened the file in PDF Creator v11.30.1 which did not crash.

Procedure to trigger the crash:

Open https://books.libreoffice.org/en/ -

Clicking “Download PDF” button opens https://nextcloud.documentfoundation.org/s/rbd2ipG6RP8F779

I click the three dots on the LH side of the black bar and downloaded the file.

Opening that file crashes Acrobat Reader.

I do have Visual Studio on this machine but I don’t use it, so I don’t know how to export the call stack. I did notice that after the first dozen or so entries the same 8 entries were repeated over and over again.
