Stop saying: “rOlLiNG rELeaSe iS nOT fOr YuO”. This has nothing to do with the rolling release model. Updates on rolling release should never touch userspace, never change any settings in your ~/.config directory.
Plasma update messed things up. It shouldn’t have touched userspace, like updates typically don’t, but it did. Blame KDE for that.
The OP is entirely right to complain about it, but he is complaining on the wrong forum. There was nothing EndeavourOS could do about this fiasco.
And I respect your right to be wrong.
