I have the same problem with this indicator. I searched and asked questions, only to be directed to similar indicators that appear to have the same coding because they also froze my trading platform. Luckily I decided to search the web and came across the source of this ZigZag indicator. Folks had the same problem and the creator updated with this version.
You should have no problems going forward.
