Description
This is the same issue I reported in MDEV-13246, opening a new issue as the old one was closed as fixed and I'm still experiencing the issue with the latest stable release.

To answer questions which were asked in the previous issue:
- I have never disabled foreign key checks.
- The most recent DDL was weeks before.
- I don't know how to reproduce it.
I didn't have binlogs enabled when it happened.(EDIT: I did have binlogs enabled)- I'm not using a cluster, it's a single machine database.
I have attached my.cnf.
