Problem with equations inImpress

English
#1

Hello,
I am writing to you about an issue I encountered today. Specifically, after launching a presentation in LibreOffice Impress, some basic mathematical symbols (+, -, =, etc.) were missing in the equations, and instead, empty squares were displayed.

When entering the equation editing mode, everything displays correctly.
However, I cannot edit the equations (the equation is read-only). Math does not respond when I press the ‘Edit Document’ button. When I open the file in the tmp directory, the equation opens normally, and I can edit it. The problem concerns LibreOffice version 7.6.2.1 on Kubuntu 23.10 system. I would greatly appreciate your help.
Best regards

Here’s what the equation looks like in Math

Do you have the correct version of the fonts, Liberation (?), Open Symbol (?), installed on the display computer?
