I am usually be the one asking question, and this time, let me be the one answering a question
"Has went" is grammatically incorrect as "has" and "went" are both verb, and under normal circumstances is no more than one verb allowed in a simple sentence.
If you are trying to express a tense, for instance present prefect tense, then you have to change the 2nd verb into adj by making it into participial, then it will be changed from
went to gone
then it would be " he has gone"
but please be caution when using this sentence. Although it means he has left, it might also mean he "passed away"
Any teachers are welcome to correct my explanation
