Mine craft launcher turns grey when I attempt to load it

I’ve recently bought a brand new MacBook and I bought Minecraft from the official site too, everything was working smoothly up until a few days ago.

Now, whenever I go to click on the grass block to open Minecraft launcher where I’d go a click the play button, it simply just turns grey and doesn’t respond for ages.

I’ve tried everything, I’ve deleted the game entirely multiple times and nothing is fixing it.
