HELP: VCR ejects tape right away

Toshiba DVR620KU (2012) Rarely used and not even dusty inside.

Hello everyone, so I have a problem and I'm not sure I can fix this so I'm making an attempt for suggestions! See video of problem here: https://youtu.be/cFIHODIXZls

The VCR accepts the tape, brings it to the upper cylinder, then ejects it without reeling the tape back in. So I have to help it back out of the VCR after confirming it's still not working.

I think I've narrowed it down to a few things:
1. It's rarely been used so there's nothing that's worn out.
2. It's very clean inside, nothing really to clean.
3. Mechanically everything is moving fine.
4. I'm guessing it's a sensor: "If the microcontroller were detecting an abnormality, then it would abort instantly but would most likely try to unload the tape before giving up but not in all designs. It is possible that if the expected behavior is not produced by the end/beginning-of-tape sensors during cassette loading, an abort could be initiated. Therefore, these sensors could be suspect. In some cases, the mode switch may be dirty or faulty. A gear may have broken some teeth or slipped a couple of teeth and the timing relationships may be incorrect. There may be a microswitch that is controlled by the cassette basket position and this may be defective or dirty."

So that's what I've narrowed it down to.
Thoughts here?
Thanks
