Error: update "core_store" - after linking slug with title

Hi, I made a change in the slug to link it with title and now I cannot even start the server now. Can anyone explain me a little bit the error message to see how I can fix it.

error: update “core_store” set “key” = $1, “type” = $2, “value” = $3 where “key” = $4 returning * - could not access status of transaction 0
