In a Flatpak or Snap sandbox the application cannot read just any file 
it wants.

I suspect Evolution is getting the attachment filename and attempting to 
just read it off disk. Which will not work in the sandbox. It has to go 
through some sort of portal process to get access to the file.

This is either an Evolution issue, or if Evolution has decided to never 
officially support sandboxing, a snap/flat packager issue.

It will probably be fixed automatically once Evolution ports to GTK-4.

There's this issue which links to a lot of other stuff:
