Why doesn't MTP Work

[AC Question]

So I got a new phone and I was trying to put some music on it from PC but MTP doesn't work. I have looked at other posts and have tried a lot different things, like 3 different cords and none of it has worked. I tried PTP and it works but I can't move music. Can somebody please help because my only two other options are one by one file transfer through bluetooth or by uploading it to my google drive, but my internet is super slow.
