Stuch at the “Activation of the necessary extension”

Hello,
We use the free All in One Migration plugin + the paid unlimited extension because our backup is 1.1go. All was good but it stucks at “The activation of the necessary extensions is finished.” and we see error in JS Consol as you can see here : https://snipboard.io/gYcsaw.jpg

And here is PHP limit : https://snipboard.io/4yp9J1.jpg

My client uses the hosting Infomaniak

What could we do ?

Thank you.
