While EXT:solrfal takes care of invalidating a sys_file's entry in tx_solr_indexqueue_file when updating its meta data, it's not doing that when renaming the file via the rename dialog in the file module.
This extension does that.
composer require kitzberger/solrfal-rename
Make sure to set at least the checkbox for flush_on_rename. The 2nd checkbox for flush_on_metadata_update might be necessary to check as well when using only the page context for indexing files.
