After automatic 6.5 update, vimeo does not work

Hi
Last night there was an automatic update of wordpress to 6.5
I use the twenty twenty theme.
This morning, no video is displayed anymore.
I use the native vimeo embed.
It says that the content cannot be embarked.
I am just a basic user, no development skills.
And this is crucial as I am lauching a campaign for my book next week

Thank you !
Carole
