Constant Exceptions from DefaultLanguage While Debugging

## Describe the bug
I'm attempting to see if I can resolve an issue with the notification feature. However, I keep having to dismiss the following exception over and over again, without end. It seems there's a timed task that keeps executing it.

## Software Versions
- DNN: 09.11.00
- Module: 06.05.04

## To Reproduce
Steps to reproduce the behavior:
1. Clean install of both DNN and the blog module.
2. Make sure the site is in Debug mode.
3. Add a page and add the blog module to the page.
4. Add a new blog.
5. (Optional) Create a new blog post.
6. {Optional) Create a blog post comment.
7. Open Visual Studio (2022) and open the Blog source code.
8. Attach to the `w3wp` process, and wait.

## Expected behavior
Nothing happens. It just sits there.

## Actual Behavior
Every few moments, seems to be maybe less than a minute, the exception keeps occurring, preventing all other kinds of debugging and development.

## Screenshots

## Error log
No errors are logged anywhere that I can see.

## Additional context
None.
