The could have at first but they lost their chance.They dont want to understand because they cant believe Jn 12:39
39 Therefore they could not believe, because that Esaias said again,
40 He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them.
God is against them being converted, so they cannot believe, they doomed friend
And I showed you the reason for vs. 40
All of this plays into the use of the word "therefore" as found in this verse. The only reason—the explicitly stated cause—for those who "could not believe" is their prior commitment to unbelief. They cannot now believe because they would not believe when given the chance. What John cites from Isaiah 6:10, in the following verse, is in that very context.
