Welcome, no unfortunately i don't know what happened. Can you provide a very small example that compiles and has just one line of text but reproduces the problem? Can you append the log file with that example to your forum post?
Does it work with a different font?
The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.
The problem happened only for CJK (Chinese Japanese Korean) user because only they have vertical writing v.s. horizontal writing....for vertical writing we need to rotate the font and everything goes the same as horizontal writing.....the rotation is provided automatically by the font specification....
