Maybe an only Mac issue, open instantly on:
Version: 24.8.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: a22ac6caece8da5add6800bdfba9865bdcfde064

Locale: es-ES (es_ES); UI: en-US Calc: CL threaded

Have you tested in Menu/Help/Restart in Safe Mode.

Opens in 5sec on Win10. But does not appear to actually use the embedded font(s). Fallback font(s) look nothing like the thumbnail in the archive.

Version: 24.8.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: 2eb428a8890dda29fbdc8b639fc1377080fab59f

Opens fast on Linux:

Version: 24.8.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: 3cb1ed4339fc9aec414c0f112a69705a7a4d9cc6
CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: threaded

On macOS, takes about 25 seconds before I can edit the document:

Version: 24.8.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: ef6ff2df2e1286974da2f344aa3b8e3ae9093a79
CPU threads: 2; OS: macOS 13.2.1; UI render: Skia/Raster; VCL: osx
Locale: fr-FR (fr_FR.UTF-8); UI: en-US

also reproduced in 7.5.9 and 7.6.4.

Not reproduced in:

Version: 7.3.3.2 / LibreOffice Community
Build ID: d1d0ea68f081ee2800a922cac8f79445e4603348
CPU threads: 2; OS: Mac OS X 10.16; UI render: default; VCL: osx
Locale: fr-FR (fr_FR.UTF-8); UI: en-US
Calc: threaded
(actually macOS 13.2.1 as well)

-> regression
