TypeError: Failed to fetch at c when trying to attach files in SPFx

Unfortunately, with intermittent issues like you're having I'm not going to really be able to help you. I can suggest a few things:

• Verify that you actually got a value in the add method before trying to retrieve the new item
• Don't "throw" and error from the catch, that's just creating a situation where you can't debug, use console.log instead... i get that you're sending your errors to a list so you can review them but throwing an error here is going to make it pretty difficult to debug the issue on the user's machine, you need to see real time what's happening.
• Add some debug or info-based console logging in the flow of the code so that you can (on the user's machine) see which of these calls is failing.

Good luck!

Are you able to open up dev tools (F12) and see what the network calls says?

That's likely a race condition then, so you may need to restructure your code.
