Saw a similar issue on Arch recently, my guess is that the sandbox
binary (I don't remember its name or path) is missing the execute
permission bit.
Not sure how to fix that on Guix, since modifying a store item is
generally a big no-no. You could maybe write a quick and dirty package
that takes ungoogled-chromium as its only input, copies it (or just
creates symlinks?), and runs chmod +x on the sandbox binary.
That way you don't have to recompile the whole package.
