ChatGPT app on my mac freezes when turning on

Hello everyone,
I downloaded the chatgpt app to my computer.
It worked fine for a few days.
Now when I turn it on it blocks the computer and I have to force it to close.

At first I thought the problem was maybe that I was using it on my iPhone at the same time but after turning everything off, restarting the computer and starting it only on the computer I still have the problem.

My computer is a Macbook M4 Pro and from what I’ve read it is supported.

Especially since, as I wrote above, the app worked for a few days.

Does anyone know the reason?
