Hello =), I have tested all regexes in the project, and find this regex may be stucked by input. For example, the following code would cost over 30 seconds.

var testInput = "~&aF~&aF~&aF~&aF~&aF~&aF~&aFxDHD#";
hasStrikeSyntax(testInput);

LOL great 🤣

Then it should be fixed. It could be used in DOS attack.

Thank you for your persistent test @2bdenny 💯
