The warning:

(process:3380): GLib-GIO-WARNING **: 12:47:10.778: Unexpectedly, UWP app `HaukeGtze.NotepadEditor_1.795.1.0_x64__6bk20wvc8rfx2' (AUMId `HaukeGtze.NotepadEditor_6bk20wvc8rfx2!notepad') supports 182 extensions but has no verbs

I think the part before the word 'Unexpectedly' is the time, but what does the rest mean?

The last thing I was doing before this started was installing canvas with npm install canvas --save.

So is there a way for me to stop this?

I also noticed it says NotepadEditor there but what does that have to do with anything? It doesn't crash the process, and doesn't seem to affect anything, but it's annoying.
EDIT : it was caused by require('canvas') rather than installing it. So how can I require it without getting the warning?

I encountered similar problem but with "Microsoft.Print3D" and "Microsoft.DesktopAppInstaller" instead.

The cause:

IDK xD. It does say in the https://github./frida/glib/blob/master/gio/gwin32appinfo.c#L3477 niry posted before, that:

...for 100% correct handling we (GLib and GIO) need to remember which extensions (handlers) support which verbs, and each handler gets its own copy of the verb object, since our design is handler-centric, not verb-centric. The app also gets a list of verbs, but without handlers it would have no idea which verbs can be used with which extensions.

As of why it has no verbs, I suspect it has something to do with registers and installation due to the solution I provided below.

My Solution: Reinstalling the problematic app

Before you begin, this only fixed my problem with Print3D and made the problem with DesktopAppInstaller worse; it now says "Failed to open manifest..." and I had to reinstall it, which also removes the problem with canvas.

1. Run Powershell with Administrator privilege
2. Get-AppXPackage "HaukeGtze.NotepadEditor" -allusers
3. If it exists, jump to number 4.

or

2. Get-AppXPackage -allusers
3. Find the problematic one (HaukeGtze.NotepadEditor) and note the NAME (not the package full name).
4. Get-AppXPackage [name here] -allusers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

I had the same problem when using Python weasyprint package. It was plaining about Windows PDF X app. GLib-GIO-WARNING **: 11:31:57.620: Unexpectedly, UWP app `6760NGPDFLab.PDFX_1.3.13.0_x64__sbe4t8mqwq93a'. I simply uninstalled the app and the problem went away.
