After running into issues with Components disappearing, I turned off Live Coding as was recommended in other posts. I ran into an issue with the Mover and Grabber Classes no longer showing up when trying to add, and after much troubleshooting, I ended up deleting and recreating those classes, following the tutorial steps.
Now when I try to use the Grab and Release functions in the Grabber Class, they no longer show up in blueprints.
I’ve tried Building/Rebuilding in VSCode, refreshing the Visual Studio Code Project, closing out of both Unreal Editor and VSCode, rebooting my machine… nothing seems to work.

Thank you for any help you can provide!
