NASA has convened an Anomaly Review Board to determine the cause & corrective action. Here's a video of the qual model Filter Wheel in action.

Well, they should have taken my advice on using Penrite instead of using Amazon Basics!

Selecting a lubricant that will work for 20 years, in a vacuum, not contaminate optics, and remain slippery at cryogenic temperatures is no easy task.

I went on Penrite's website and tried to select an oil for JWST. Under vehicle type, "Space Telescope" was notably absent.
