Hello! I'm having an issue where PowerToys won't even open. I have tried everything (outside of a fresh install of windows) - run as administrator, checking windows update, uninstall, restart, install, restart, etc, etc.
When I open windows event viewer, I get the same error every time I try to open the application... any ideas?

Also, in case the photo didn't go through, here's the error text:
Faulting application name: PowerToys.exe, version: 0.91.1.0, time stamp: 0x682ac6ff

Thanks for sharing the error details — you're not alone in facing this issue with PowerToys v0.91.1.0. Based on recent reports on GitHub, this crash on startup with Exception code 0xc0000409 appears to be affecting multiple users, and it's likely a bug introduced in this specific version.

Here's what you can try to resolve it:

1. Downgrade PowerToys

Many users have reported success by rolling back to a previous stable version (e.g., v0.89.0 or v0.90.1):

Uninstall the current version.

Download an older version from the PowerToys GitHub Releases page.

Install it and see if it launches properly.

2. Clear PowerToys Settings

Corrupted settings can cause crashes:

Navigate to:
C:\Users\<YourName>\AppData\Local\Microsoft\PowerToys

Delete or rename the settings.json file.

Try launching PowerToys again.

3. Check for Conflicting Software

Some users have reported issues when using PowerToys alongside:

Custom shell extensions

Third-party window managers

Certain antivirus software

Try disabling or uninstalling these temporarily to test.

4. Use the Microsoft Store Version

If you installed via GitHub or winget, try switching to the Microsoft Store version, or vice versa.

5. Monitor GitHub Issue #39745
