child theme customize “Please wait this might take a while”

I have created a child theme of materialis but when I try to go into the customize area I get the spinning animation and a “Please wait this might take a while” message.

I looked in the console and saw two errors detailed below

Having searched around, it seems like the function andSelf() was removed from jQuery version 3 and the addBack() method should be used instead. https://api.jquery.com/andself/

Is there any way to get the customize area to work in a child theme as it seems to work fine in the main materialis theme.
