✔️ Expected Behavior

The settings window without an error popping up

❌ Actual Behavior

PowerToys Run appears to experience a fatal error. Opening settings again doesn't cause any further errors and while Alt + Space does bring up PowerToys Run, it is not functional and doesn't show any results.

Other Software

No response

If you don't run as admin does the same issue happen?
Do you have multiple users on your system?

The same issue occurs when I don't run as admin. I only have one user on my system (other than service accounts, IIS, etc.) though I should mention that I previously had a different user on my machine which I migrated to an AD account using ForensiT's Domain Migration tool somewhere in march. I don't remember the error popping up before the last update though.

We should verify if we need the following line and should we crash when it fails.

PowerToys/src/modules/launcher/PowerLauncher/PublicAPIInstance.cs

Line 40 in 19952ef

DesktopNotificationManagerCompat.RegisterAumidAndComServer<LauncherNotificationActivator>("PowerToysRun");

In general, we should review PublicAPIInstance.cs

@mykhailopylyp
if I'm not mistaken, that is only used for the Service plugin, to open a toast notification after starting/stopping a service.

Hey, just wanted to update this issue and mention that I am still experiencing the error under 0.41.3.0. The exception remains the same.

With #12285 merged, Microsoft.Toolkit.Uwp.Notifications library will be removed.
Let's see if will fix this issue.

Hi @marnicgit ,

If you open the Registry Editor, navigate to HKEY_CURRENT_USER\SOFTWARE\Classes\CLSID\{dd5cacda-7c2e-4997-a62a-04a597b58f76}\LocalServer32 and right click to check the permissions.
In normal conditions, your user, the System account and Administrators would have access to it, inherited from CURRENT_USER\Software\Classes.

Perhaps the domain migration tool misconfigured some registry keys.

[latere-a-latere]

@jaimecbernardo You might be onto something:

I'm guessing that this is mostly my computer being borked rather than a hard bug in Run, but I'll keep the issue open until I've tested out the merge of #12285.

Resolved with the release of v0.45.
