Commercial airliners crash into mountains even with the ground proximity warning actually.
Out of my memory, in Nepal alone all of the following happened despite ground proximity warning Tara Air 197 in 2022, Paki 268 and Thai 311 are some I can think of but I'm sure there's more.
Problem is: even if GPW is activated pilots may not be trained correctly to handle the warning, they may distrust the warning due to it being active concurrently with other malfunctions, lack of spacial awareness, puzzlement/stress, etc.
