I thought one of the things with New Space is that Commercial off the Shelf parts were being used more and more. I’m assuming if that’s a case there have been more mishaps.

How does SpaceX tackle this with both the rockets, and the thousand of Starlinks.

Rad Hardened parts are "Commercial off the Shelf" parts. VORAGO, TI, and others provide rad hardened parts via vendors like Mouser and Digikey. They're just much more expensive.

The threat of radiation is severely overblown.

NASA is overpaying for underperforming "hardened" hardware that performs no better than non-hardened. You can see this yourself with the mars helicopter ingenuity.

If you are desperate for extra safety then just include multiple computers, literally what spacex does.

The BAE Systems RAD750 radiation-hardened single-board computers used by Orion are commercial products but typically costs between $200,000 to $500,000 per unit

You should read the article. The problem is the destructive effect of radiation on the human body, not on the space hardware.
