POE2 : Start game with Smith of Kitava, then game crash everytime. But other characters are OK.

I have few characters in Dawn of the Hunt and they can play and have fun.

When I chose my Smith of Kitava and click start game, it crash everytime.

The level of my Smith of Kitava is 96.
After I changed my passive skill to Living Weapon yesterday, and got into T15 map to test the skill, then game crash.

I tried to reinstall POE2, but I still cannot chose my Smith of Kitava to play. Game crash everytime.

However, my other characters still can play.

Has anyone else experienced the situation as me?

Still cannot play my level 96 Smith of Kitava, why?
