search or index table failed when we try to index all fields when we have enabled user field "Last modified by"

[chillpilllike]

Indexing failed error shows up when we set global and search or index table failed when we try to index all fields when we have enabled user field "Last modified by"

The index and search works normal when we do not search anything in all fields except user field "Last modified by"

The index table fails to create in all cases untill we delete the "Last modified by" field
