Error when typing equations in presentations.

[raykostantchev]

When ever I type an equation in Presentation mode using the shortcuts, then it gives an error saying
"An error occurred during the work with the document. Use the 'Save as...' option to save the file backup copy to a drive"

But this only happens if I use the typing shortcuts in equations. Say I type "t _ i [space]" then it will crash when I press [space]. Otherwise it I click on create an equation with a subscript, then the document has no problem.

When I run it it gives me

QLayout: Attempting to add QLayout "" to CTabBarWrapper "tabWrapper", which already has a layout

and a few more of the same Cambria Math errors.
But it does not give an error or change in output when it crashes with the above error message. Finally, typing equations in the Document mode works fine with these equation shortcuts.

This is on Fedora 37 with version 7.2.1 of desktop editors version on Flatpak and also the same issue on the same RPM version. Let me know if you need more system info.

I fixed it for myself by downgrading back to version 7.1.1-57 on the RPM repo.
