Upload large size images

Hi! Since I’ve installed the new version of WordPress (6.0), I am having an issue when I upload large size image.

So, let’s say I’m uploading a picture (3000 x 3000) – Usually it would load and then appear in my gallery as 2560 x 2560 with the file added _scaled to the name.

Since the update, I receive this error message:

“Le serveur ne peut pas traiter l’image. Cela peut se produire si le serveur est occupé ou ne dispose pas de suffisamment de ressources pour terminer la tache. Téléverser une image plus petite peut aider. La taille maximale suggérée est de 2560 pixels”

Funny thing is, when I refresh the page, the image is in the gallery and scaled. But it’s a bit annoying as before it was doing it by itself and I could keep working on my post. But nowz I have to receive this error message, refresh the page and keep working. The worst is that if I wanna add 10 pictures in a row, I have to refresh and reupload 10 times.

I tried to deactivate all my plugins to verify it wasnt one of them that was faulty, but nope, it does the same pattern.

Anyone can help?
