I'm experiencing a similar issue and the error I get in the terminal is this

./LinuxPowerToys-0.9-x86_64.AppImage 
Gdk-Message: 11:30:28.585: Unable to load  from the cursor theme
Gtk-Message: 11:30:28.626: Failed to load module "canberra-gtk-module"
[ERROR:flutter/runtime/dart_vm_initializer.cc(40)] Unhandled Exception: org.freedesktop.DBus.Error.UnknownMethod: Object does not exist at path “/org/gnome/Shell/Extensions/TilingShell”

The gdk-message's are on load and the error is when I click the "+" button for the layouts. This is on Ubuntu 25.04
