I can't confirm with

Version: 25.8.2.2 (X86_64)
Build ID: d401f2107ccab8f924a8e2df40f573aab7605b6f
CPU threads: 12; OS: Windows 11 X86_64 (build 26200); UI render: Skia/Vulkan; VCL: win
Locale: de-DE (de_DE); UI: en-GB
Calc: CL threaded

Tested several times

Perhaps only a problem with Linux or resolved in actual version. Brayden, could you please retest with LO 25.8 or actual master?
=> NEEDINFO

(In reply to Dieter from comment #1)
Sorry, I am not a computer person, what is the actual master? And I don't know if it means anything, but I am not on an administrator account for my computer.
Version Information:
Version: 24.2.7.2 (X86_64) / LibreOffice Community
Build ID: 420(Build:2)
CPU threads: 8; OS: Linux 6.14; UI render: default; VCL: gtk3

Comment 3 Dieter 2025-11-19 20:55:24 UTC
If you're not the adminstrator it's of course not possible for you to test another version. Perhaps only related to Linux.

I attempted to reproduce this issue on Windows using the same steps, but I couldn’t trigger the freeze.

System Details:

OS: Windows 11

LibreOffice: 25.8.2.2 (X86_64)

Result:

Writer remained responsive.

No freeze or stall.

No “LibreOffice isn’t responding” dialog appeared. CPU load stayed normal and could not reproduce any freeze or hang.

I cannot reproduce the issue on Windows with LibreOffice 25.8.2.2.

Brayden: on Linux, you might be able to try an appimage version: https://www.libreoffice.org/download/appimage/

This is what I did to cause the error

This bug is caused with only 3 sections, no more and no less. Also you absolutely have to press the enter key at least once for the bug to occur. I have reproduced this multiple times included is an attachment for what I did.

This is what happens after it crashes.

So, maybe the bug is only on linux but I am showing you that it happened.

Comment 12 Xisco Faulí 2025-11-27 15:15:33 UTC
Considering the issue has been around since 3.5 I would suggest to lower the priority a bit to 'high'.
