There is an issue on my WordPress website (TypeError: Cannot read properties of)

Hi
Here is my WordPress website situation

1. version: 6.5.3
2. litespeed cache version: 6.2.0.1

I have this issue after I installed the Litespeed cache plugin on my website

2. (anonymous) @ e70348ff72feda1e0a282fc4292496e7.js?ver=7f3aa:12

The content of the file (e70348ff72feda1e0a282fc4292496e7.jss) is below

1. const iframeStylesheetStub = iframeStylesheet.cloneNode(!0);
