Background of the issue:
I am experiencing repeated 500 server errors on our website hidden link. A technical audit identifies the WPML plugin (sitepress-multilingual-cms) as the main cause. The audit report highlights repeated Fatal PHP Errors in our logs, including 'Class "WpOrgRequestsExceptionHttp" not found', 'Class "WPML_REST_Factory_Loader" not found', 'Interface "IWPML_Action" not found', and 'Trait "WPMLCollectSupportTraitsMacroable" not found'. The probable cause is a corrupted or incomplete installation of the WPML plugin, likely due to missing files, incorrect permissions, or a failed update.

Symptoms:
Repeated 500 server errors causing high server load and site crashes. Fatal PHP Errors in logs related to WPML plugin.

Questions:
Could you please provide guidance on the safest and most effective way to resolve the corrupted WPML installation?
How can we fix the corrupted installation without losing any translation data?
