PHP 7.2.33
Test site is on the same server as main, both have the same settings. But only main one has this issue.
EDIT:
If you have similar problem check features in back office by CTRL+F and look for --. There were empty values which were deleted from table feature_value_lang, but they were left inside feature_value table.
