I'm currently runnig Umbraco 9.4.2, when saving, deleting or unpublishing new content, I'm getting the below error - this seems to relate to the re-indexing of the site. Using the 'save and publish' option seems to work fine however. I've tried installing the Lucene.net 4.x.x packages, however the issue still seems to be occurring. Can anyone shed any light on this please?

  Server error: Contact administrator, see log for full details.
