So I was using discord_arch_electron for a long time now, and during an update I saw this error. I decided to uninstall the package and reinstall it again but the error showed up again.
I have to use the default discord package for now which installed properly without any issues, but any other discord package that contains a newer electron version is broken and the same error mentioning “libicui18n.so.73” shows up.
Uninstall again, delete it from the yay cache ~/.cache/yay/discord_arch_electron and reinstall (or you could just cleanbuild it). Will try it here now.
:Edit: Just installed discord_arch_electron, works fine.
