Description
Devices CPU usage spikes when working on a template. I noticed a larger number of python processes are run in quick succession which is using the CPU. I have no issues if I disable the extension. I've attached a screen shot of resource monitor.
Environment
- Windows 10
- VS Code 1.71.2
- Python 3.10.1
- cfn-lint 0.66.1
Actions: Editing of a Cloudformation template with the linter extension enabled
Thanks in advanced for any assistance.

Research direction
No source files, tests, or entry points are identified in the report. Reproduce the CPU spike on Windows 10 while editing a CloudFormation template with the extension enabled, compare it with the extension disabled, and use the reported process behavior to define the regression check and completion criteria.
