To fix the problem, we need to modify the regular expression to remove the ambiguity that leads to exponential backtracking. Specifically, we can replace the problematic part
[^\s"*:<>?|]+with a more precise pattern that avoids nested quantifiers. One approach is to use a non-capturing group with an atomic group to prevent backtracking.(?>...)to prevent backtracking within the group.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
