I have this map made in QGIS3, imported in as a SVG, without the text labels which in Inkscape onto of the Map layer.

I then saved it as a SVG and when importing it into MS Word or PowerPoint everything is fine besides the text disappears completely with the glow of the text remaining, works fine when saved as a PNG, however this is normally enough as a PNG but I require this for a poster so the depth of detail difference is making a bigger difference then normal, as normally the PNG would be sufficient. 

System: Windows 10, Inkscape 1.2.2 (732a01da63, 2022-12-09).

Failed Import attached (Please ignore its blurriness that just me failing to screen capture it at a high quality) and the SVG.

Thank you for any help :)

Just a wild guess - as I can´t check in MS Word/PP just LibreOffice - but has the same issue with the thick white outline you put to the text.

To make it work I´ll have to convert all text to shapes on a duplicated file (to have a backup) by selecting one text object - then Select Same->Object Type then call Path->Union - and then Path->Stroke to Path. Save again and load into MS Word etc. 

Thank you very much sir this has done it exactly! 

Conveniently this has come to my rescue in another manner.... MS Word turned off the 'Do not compress images' feature which I turned on so half of my PNGs have become ugly now I can change them with the fixed versions of SVG and no longer rely upon the evil MS Word product to not destroy the entire document at a whim.
