If Raycast or node process are using almost all CPU available in your machine, you should sample their processes in the Activity Monitor and send us the respective file(s) so we are able to troubleshoot the issue causing this.
This is how you do it:
Open Activity Monitor and filter for “raycast”.
Select Raycast process in the list and click the icon with the three dots in a circle.
After the sample is taken, press “Save…” to download the sample file.
Follow the exact same process to sample the **Raycast Helper (Extensions) process.
