I see the error in Version: 24.8.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: 39048e0c0e9af455197ff57cc2947f8fb23e8542
CPU threads: 32; OS: Windows 10.0 Build 22631; UI render: Skia/Vulkan; VCL: win
Locale: de-DE (de_DE); UI: en-US
Calc: threaded

It is OK in Version: 7.6.4.1 (X86_64) / LibreOffice Community
Build ID: e19e193f88cd6c0525a17fb7a176ed8e6a3e2aa1
CPU threads: 32; OS: Windows 10.0 Build 22631; UI render: Skia/Vulkan; VCL: win

I have tested it with template "Blue Curve".

It is likely the same problem as in bug 159931. I see the same error, that ppt\slides\_rels\slide1.xml.rels refers a part "../slideLayouts/slideLayout0.xml" which does not exist.
Comment 2 Regina Henschel 2024-03-02 00:58:23 UTC 
The 0 in slideLayout0.xml comes in via 
PowerPointExport::GetLayoutFileId()
because mLayoutInfo[ nOffset ].mnFileIdArray.size() returns 0.

The call of GetLayoutFileId comes from
PowerPointExport::ImplWriteSlide() and therein from preparing the parameter values for addRelation() in line#1380.

That is in file sd/source/filter/eppt/pptx-epptooxml.cxx.
Comment 3 Regina Henschel 2024-03-17 14:10:41 UTC 
I set this as duplicate to but 159931. That on is fixed. The fix will be available in version 7.6.7 and 24.2.3. You can already test it in a daily build. You can install a daily build alongside a regular build.
https://dev-builds.libreoffice.org/daily/master/

If you find, that your problem is not fixed in these builds, please set the bug status back to NEW.
