Cannot stop Lost Mode : it's pending while device is online

Hello, I have a problem with my iPhone 12 (iOS 18.7.1), I cannot stop the lost mode.

I thought I had lost my iPhone so I logged in https://www.icloud.com/find/ and I put my iPhone in lost mode.

It said that my iPhone was offline and that lost mode was pending...

I found my iPhone in my house (connected to wifi), it wasn't locked with the message I add but I couldn't use Apple Pay: it says that I need to connect to my account but when I click on the button nothing happens at all.

I went to the Find my iPhone app and clicked on the lost mode to deactivate it. It is now saying that lost mode will be deactivated when the iPhone will be connected to the internet but it is.

On https://www.icloud.com/find/ it says the same thing: stop lost mode is pending.

What can I do to solve this problem?
