I have latest Inkscape 1.2.1 (2ed6d7ae0b, 2022-08-22, custom), installed via snap, on up-to-date fresh install of Ubuntu 22.04
Open Inkscape and then menu 'File / Open...' works fine. But if in Ubuntu File manager I right-click a SVG file and select Inkscape via "Open with another application" nothing at all happens. Selecting other apps instead (e.g. Gedit) no problem.
Anyone know how to fix this?
And whether this is an Ubuntu-related issues or rather an Inkscape bug? In the latter case I will search their issue tracker and file a bug if I can't find anything related.
