I too am having this problem, and Daisyyy is correct.....
The SVG file is downloaded from a free software site (Vecteezy) to my PC Windows 10 system (tutorial videos show these images arriving to the folder as SVG files)
When the folder is opened, listed under the "Type" section where it should say SVG, JPEG, etc. it simply says "Affinity Publisher File", with the orange Affinity Publisher logo in the "Name" section. Maybe it's still an SVG file without that extension showing, but trying to "Open Local File" to bring it into a different vector editing tool (Gravit), it says the file is not supported.
Double click on that named file in the folder and it opens Affinity Publisher with the image.
I can then export that page as an SVG file, which is then showing in the folder as a "Chrome HTML document" under the "Name" section
I can then "Open Local File" to bring it into a vector editing tool (Gravit) and it seems to be editable at that point, assuming it's an SVG file without showing that extension in the Name
But really? Too many steps to get from Vecteezy to Gravit (or whatever sites/tools others are using.)
It seems there's a setting added to the system by Affinity Publisher that says all SVG downloads will be saved as "Affinity Publisher File" for easy opening in that program.
The question is how do you find and disable that setting to allow use of other programs and simple filing of these images as SVG files?
