Launch failure "basic_string::_M_construct null not valid"

▶ flatpak run com.mojang.Minecraft

{{terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_M_construct null not valid}}

I'm trying to run the Minecraft launcher in a Flatpak container. Although it works on one system, it fails with the above error in another. It seems to be a launcher bug. It crashes instantly and no window appears.
