Swiftlint hangs after processing all the files

Describe the bug

I have written a custom rule to match constructors with more than 5 parameters.

custom_rules:
  constructor_parameters_count:
    included:
      - ".*\\.swift"
    name: "Constructor Parameters Count."
    regex: '^\s*(init\((\s*\w*\s*\w*\s*\:\s*\w*(\s*\=\s*(\w|\.|\(\))*)*,){5,}(\s*\w*\s*\w*\s*\:\s*\w*(\s*\=\s*(\w|\.|\(\))*)*)\))'
    capture_group: 1
    message: "Too many constructor arguments."

Swiftlint hangs after processing all the files.

Complete output when running SwiftLint, including the stack trace and command used

$ ../Pods/SwiftLint/swiftlint lint --strict --benchmark

hangs on

Linting 'TasksUITests.swift' (1591/1591)

• Are you using nested configurations? no
• Which Xcode version are you using (check xcodebuild -version)?
  Xcode 13.4.1
  Build version 13F100
• Do you have a sample that shows the issue? just the regex

Reproduce the hang with the supplied custom_rules configuration using ../Pods/SwiftLint/swiftlint lint --strict --benchmark, focusing on the custom constructor-parameter regex. Compare the run with that rule disabled, then trace custom-rule processing after the final file is reported. Done means linting completes instead of hanging and the configuration still reports the intended violations.
