Slider Revolution JS ERROR

Good Afternoon, I have an issue with the slider revolution on my home page. Below is a screenshot from my mobile phone giving me an error of the slider revolution. This has never happened before and just wanted to get to the bottom of it and for a solution to be provided. Once you refresh the page, the slider comes back, however if you refresh it again, the slider may be gone. Once again, it didn’t used to be like that and just wanted to get some help regarding this issue being fixed. I understand that on a laptop it may appear, but once I keep refreshing it the error pops up on mobile and I do not want that to be the case. Thank you for taking the time to read this. I have disabled the plugins that don’t come with the theme and nothing happened.
