Json data loading too slow?

Hi all.
I’ve had this problem before , with my frontendmentor projects , when I submit them.
The screenshot is taken I guess a second or two before the JSON data is loaded/fetched.

I’m hoping someone can help.
Here’s my github:

I’ve tried using async/await and fetch, I’ve tried just fetch with no async/await, and neither seem to be fast enough?

Thanks

This is what’s happening.
My solution looks the same as the design, but just loads too slow I’m assuming?

Any help would be very much appreaciated.
Thanks

I’ve tried everything that I can think of , but I can’t solve this.
Great, I must be an idiot I guess, because nobody else seems to run into this problem (google turns up to my freecodecamp forum questions).
