@CaptainTammy -Is this specific to one platform or a version?
Can you provide details about the environment?

@EsterBergen
I don't think this is platform specific as we have encountered it on both Windows and Mac versions while developing.

Environment
Platform [PC desktop, Mac, iOS, Office on the web]: PC, Mac
Host [Excel, Word, PowerPoint, etc.]: Powerpoint
Office version number: Mac 16.82, Windows 2401
Operating System: MacOS, Windows
Browser (if using Office on the web): NA

Here are the repro steps:

• Create presentation with one slide, which have a tile text box as first shape.
• Add any web based add-in, for example web viewer
• In add-in's console run:

PowerPoint.run(async context => {
    const slide = context.presentation.slides.getItemAt(0);
    slide.shapes.load('items');
    await context.sync();
    const shape = slide.shapes.items.at(0);
    shape.load('*');
    await context.sync();
    shape.textFrame.textRange.text = 'FIRST-LINE\nSECOND-LINE';
});

• Previous code should insert header FIRST-LINE\nSECOND-LINE in two lines
• Now try to read it, run in console:

Office.context.document.getSelectedDataAsync(Office.CoercionType.SlideRange, asyncResult => {
    if (asyncResult.status === Office.AsyncResultStatus.Failed) {
        console.log('ERR');
    } else {
        console.log('SUCCESS', asyncResult.value.slides[0]);
    }
});

• no console log will be printed, code is stuck and nothing happens
• if I use \r instead of \n, everything works as expected.

I wonder, if we may have similar issues in another Office APIs...
