As reported by Sprinterdriver in the 1.2 release announcement:
If a file that contains text elements are opened in Inkscape 1.2 (portableapps) - then it always pop up a message that list the fonts used.
Example
Font 'Bahnschrift' substituted with 'Bahnschrift'
Font 'Franklin Gothic Demi' substituted with 'Franklin Gothic Demi'
Font 'Gill Sans Nova' substituted with 'Gill Sans Nova'OS: Windows 10 Pro, 21H1, 19043.1645
I've tested the original version of Inkscape (downloaded from inkscape.org) and cannot reproduce at that. Therefore this looks like an issue only affected by the portableapps version of Inkscape 1.2.
**To reproduce**
* Use previous version of Inkscape to create a document that contain the fonts mentioned above (other fonts may or may not be affected).
* Run Inkscape 1.2 - portableapp version.
* Use dialog box file --> Open, find/select the file created in step 1
