Fuck Etcher.
Manjaro used to have a perfectly good USB image writer utility, but I think it got removed with some update, and for the life of me I can't remember what it was called. I think it was "borrowed" from CentOS or some other distro I've never touched. And now I'm stuck with relying on this Electron crap cause I can't find a decent, simple USB image writer tool.
I tend to just use dd.
