I found the problem:
for example meta_value for one product tabs in database:
a:1:{i:0;a:3:{s:5:”title”;s:14:”Брошюры”;s:2:”id”;s:14:”брошюры”;s:7:”content”;s:104:”<a href="https://interanalyt.ru/wp-content/uploads/2021/05/gc-2014-flyer-03.18.pdf" rel="nofollow ugc">ГХ 2014 (пдф)</a>“;}}
and its not correct in this “s:104”, “s” have to be s:106.
