PowerRename exits when it reaches an html file with connected folder

### Microsoft PowerToys version

0.98.1

### Installation method

PowerToys auto-update

### Area(s) with issue?

PowerRename

### Steps to reproduce

Given a folder with files `a_page.html`, `b_page.html`, and `c_page.html`, plus a folder `b_page_files`.

Use PowerRename to try to add `_new` to the ends of the filenames.

### ✔️ Expected Behavior

PowerRename should rename all the files it can and give you a error message about the ones it didn't rename.

Context:
It's normal for Explorer to pop up a warning when you try to manually rename an `htm`/`html` file with a "connected" folder (one with the same filename, but ending in `_pages` instead of `.htm`/`.html`.

If possible, PowerRename should give the user the option to rename such files anyway.

### ❌ Actual Behavior

PowerRename thinks it succeeded.

But it actually stopped renaming files once it got to `b_page.html`.

Here's the portion of the PowerRename log file from my bug recreation.
