Missing selection field in t3lib_TCEmain::getPreviousLocalizedRecordUid()
To fix #30469 a new method was introduced in t3lib_TCEmain to fetch the "neighbouring" translated record, if any. For tt_content this method checks for the "colPos" field in order to compare elements from the same content area. But "colPos" is not among the fields selected in the SQL query.
The solution is simply to add "colPos" in the list of fields to select when the table being handled is "tt_content".
