Splide has broken, send help!

Hey guys,

I’ve got 3 Splide sliders on this site I’m working on, they were working just fine. Then the client put the breaks on the project for a month and now I’ve come back to pick it up again, Splide isn’t working a tall.

I’ve tried restoring from multiple different backups, updating the library, replacing the code and setup of the JS and nothing is working. Can anyone help?
