Table column comments are not displayed

After upgrading to DataGrip 2025.3, the column comments no longer appear in the table structure view on the right side. I have tried many methods but none worked — even setting the introspection level to 3 (the highest) doesn't help. The Comment column is checked and visible in the Structure tool window, but all comment cells are completely empty (previously they were displayed normally). How can I fix this issue?
