Answer 1

This is base64 encoded JavaScript (usually bad when found on WordPress site)
(you can decode it online here: https://www.base64decode.org/)
Decoded it says:
var downloadButton=document.getElementById("download");
var counter=40;
var newElement=document.createElement("p");
newElement.innerHTML="You can download the file in 40 seconds.";
var id;
downloadButton.parentNode.replaceChild(newElement,downloadButton);
id=setInterval(function(){
counter--;
if(counter<0){
newElement.parentNode.replaceChild(downloadButton,newElement);
clearInterval(id)
}else{
newElement.innerHTML="JUST WAIT "+counter.toString()+" SECONDS."+"YOUR BGMI 2.3 DOWNLOAD LINK IS GENERATING"
}
},1000)
it appears that newElement.parentNode is null and that's what's causing the error.
if this is your code, and a desired code-piece on your WordPress website - try changing if(counter<0){ into if (newElement.parentNode && counter<0) { . otherwise, find where this is coming from, and remove it from your code base.
Update
Try this:
var downloadButton=document.getElementById("download");
var counter=40;
var newElement=document.createElement("p");
newElement.innerHTML="You can download the file in 40 seconds.";
var id;
if (downloadButton && newElement.parentNode) {
downloadButton.parentNode.replaceChild(newElement,downloadButton);
id=setInterval(function(){
counter--;
if(counter<0){
newElement.parentNode.replaceChild(downloadButton,newElement);
clearInterval(id)
}else{
newElement.innerHTML="JUST WAIT "+counter.toString()+" SECONDS."+"YOUR BGMI 2.3 DOWNLOAD LINK IS GENERATING"
}
},1000)
}
