Bug: PowerShell script doesn't consistently execute when theme is toggled

### Description

### Issue: The script sometimes executes and other times it doesn't.
1. There are no issues with the PowerShell script itself.
2. I'm using only one script for debug.

Below are the relevant log sections from the app's `service.log` log file, split into two parts that represent two theme toggle instances:
1. The first logs the script executing
2. The second doesn't log any attempt at executing the script
