[ufukty]

Context

• Editing a rule using Dim v4.0.1 and VS Code 1.119.0 caused high CPU use and the extension to stuck.
• The config which its frequent editing triggered the problem, has no problem after restarting Code.

  {
    "pattern": "(?<=catch\\s+\\(e\\)\\s+{)[^{}]*(?:{[^{}]*}[^{}]*)*(?=})",
    "flags": "gs"
  }

• Last printed logs in the session seems were outdated at the moment of issue:
