INTL_IDNA_VARIANT_2003 is deprecated

Hello I am facing problems with uploading files on my systems. [CODE=php]idn_to_ascii (): INTL_IDNA_VARIANT_2003 is deprecated
It seems that this problem is a problem with php in version 7.2, unless I'm mistaken, but mine is in version 7.3 Even with the update that happened a little while with version 7.4 the error persists I don't know why it started happening today Monday
