This will not work in export builds:

DirAccess.copy_absolute("res://assets/default_project_icon.svg", dir.path_join("icon.svg"))

seems like there is some workaround.

I'm not sure if global settings is where you should put the checkbox: I think the better place is to put it in the new project dialog.

Thanks, I don't noticed this. But this workaround didn't work too, so I done another workaround and it's work.

Yes, it's will be better.

May be Godots should remember user choose (.svg or .png), but I'm not sure how to implement this properly.

for this we use cache
for instance:

So it may look like:

var use_png = Cache.smart_value(self, "use_png", true)

use_png.ret()
use_png.put(new_val)

Done

Cool thanks!
