In the first one "faced by" and "faced with" are both possible. In the second only "faced by" is correct. Can you see why?

Thanks a lot, bhai. Could it be because we say:
Sb faces difficulties/challenges etc
Difficulties/Challenges face sb
and from the latter comes the passive 'Sb is faced by difficulties/challenges etc'?
