Look behind assertions are not supported in Safari. Check compatibility table here
Instead you can try without it.

const regx = new RegExp("([\\s,.:;\"']|^)("+word+")([\\s,.:;\"']|$)","g");

Example

let word="word";
const regx = new RegExp("([\\s,.:;\"']|^)("+word+")([\\s,.:;\"']|$)","g");
console.log('hello word, beautiful word'.replace(regx,'$1World$3'));
