I had the same type deck years ago, some decks have a two part door, make sure the outer door is clipped on to the inner mechanism correctly, may just have to be popped off. then re pop back on to inner door. jim d
The mechanism of these machines may not reset the head base all the way down due to dried grease. This then allows parts as the head to be up to get in the way of the tape as it tries to go in. There are also sometimes little plastic stops that break on cassette doors so that tape may drop down too far. Either of these issues can cause a problem inserting a tape. See how the reel table line up with the tape as this is an indication of where the tape is sitting. If they are in line the head base is up too far. If they are too high on the cassette then the plastic stops are broken or missing.
