I think this is an known issue.

Some problems may be similar to "GitLab migrate merge requests + issues faile #13884". But I have zero "issues" in the GitLab repo.

If there's a sample GitLab instance which can reproduce this issue....I have tried to deploy a GitLab with version 11.4.5, and created an empty repo with zero issues, and the migration is done. Maybe I need to use PostgreSQL instead of SQLite.
PostgreSQL also works.

May be version of PostgreSQL 16.6 may work incorrect?
I remove problem Merge Request, but problem still exist.
I cant public my gitlab instance.

From postgres log.

Some observations: Problem always exist with last Merge Request (by index).
