I have the same issue, I found that my optoma projector is returning two '/r' characters in stead of one at the end of a command response

If you also have an optoma projector and run into this issue, here's the workaround I'm using: https://community.home-assistant.io/t/optoma-projector/82740/13

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates. Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment 👍 This issue has now been marked as stale and will be closed if no further activity occurs. Thank you for your contributions.

I got this working with an Optoma UHD60 by adding the "name:" attribute to the Homeassistant config. eg:

media_player:

• platform: pjlink host: 10.10.10.65 name: optoma_uhd

Without "name", I would get the AssertionError. Took me an entire afternoon to figure this out! Hope this helps someone or to narrow down the error.
