This site suddenly is making an AnnotionException. Nothing was changed on the server nor de site itself, just maybe Apache / PHP updates. I tried using different PHP versions, 7.4 / 8.0 / 8.1 but all give the same error.

When I run the site locally on 8.0 or 8.1 there is no error. Can anyone point me in the right direction as to where I should start looking?

Drupal 9.4.0

DoctrineCommonAnnotationsAnnotationException: [Semantical Error] The class "DrupallanguageAnnotationLanguageNegotiation" is not annotated with @Annotation. Are you sure this class can be used as annotation? If so, then you need to add @Annotation to the _class_ doc comment of "DrupallanguageAnnotationLanguageNegotiation". If it is indeed no annotation, then you need to add @IgnoreAnnotation("LanguageNegotiation") to the _class_ doc comment of class DrupallanguagePluginLanguageNegotiationLanguageNegotiationBrowser. in DoctrineCommonAnnotationsAnnotationException::semanticalError() (line 39 of /home/avascosolar/test/app/vendor/doctrine/annotations/lib/Doctrine/Common/Annotations/AnnotationException.php).
