Hello Anaokar,
Welcome to Apple Support Communities.
We understand that you have a shortcut that you are trying to run by using Siri. If this is the only shortcut that is returning this error, we would suggest troubleshooting this shortcut. You can try something like recreating the shortcut under a different name and testing the new shortcut. These support articles should be of help:
If Siri on Mac doesn’t work as expected - Apple Support
- "Make sure your Mac is connected to the internet. Choose Apple menu
> System Settings, then click Network
in the sidebar. (You may need to scroll down.) - Make sure Siri is turned on. Choose Apple menu > System Settings, click Siri & Spotlight
in the sidebar (you may need to scroll down), then turn on Ask Siri on the right. - Note: If you can’t turn on Siri, Screen Time Content & Privacy Restrictions may be preventing you from using it. A family organizer for a Family Sharing group can set up Screen Time for a child and restrict access to Siri & Dictation. See Change App Restrictions settings in Screen Time.
- Make sure your Mac has a microphone and that it’s not obstructed by your clothing, body, or other objects.
- If you’re using an external microphone, check that it’s connected to your Mac, selected in Sound settings, and that its input volume is set high enough.
- Choose Apple menu > System Settings, click Sound
in the sidebar (you may need to scroll down), click Input, then drag the “Input volume” slider. - If you’re using a Mac that supports “Hey Siri,” make sure the lid on your laptop is open. (You can also use “Hey Siri” when your supported Mac is locked or in sleep.)
- If you’re using AirPods or headphones that support “Hey Siri,” make sure they’re paired with your Mac. (You can also use “Hey Siri” when your Mac is locked.) See Connect a Bluetooth device with your Macand the Apple Support article If your AirPods won’t connect.
- If you’re using an Apple Studio Display for “Hey Siri,” make sure it’s connected to your Mac. See Connect a display, TV, or projector to Mac."
Change a conflicting keyboard shortcut on Mac - Apple Support
- "On your Mac, choose Apple menu
> System settings, then click Keyboard
in the sidebar. (You may need to scroll down.) - Click Keyboard Shortcuts on the right. A warning icon appears next to conflicting keyboard shortcuts. Double-click the shortcut, then change it. See Use macOS keyboard shortcuts."
