I'm having the same issue and have found no solutions. Have you had any luck since?
Same error in the current release version ! 10.14.2 (18C54)
It requires two lines being typed into terminal.
1.) Open terminal and type the following and hit enter
xattr -d com.apple.FinderInfo ~/Library
2.) Type this additional line and hit enter.
chflags nohidden ~/Library
Your library folder should now be visible!
