Given key was not present in Library when saving into MariaDb

[z3fq0n]

When performing any action (edit, move i.e.) on a connection it gives the following error:

---

ErrorMsg 07/07/2022 10:55:36 Couldn't save connections file as ""! The given key '0' was not present in the dictionary.

EDIT: The first record got processed correctly, it stopped working right after Duplicating the working record produces the same error

EDIT2: I tried installing a clean install of MySQL to troubleshoot MariaDB compatibility, getting the same issue. EDIT3: Doesn't work with either localhost or on external Database server EDIT3: Same issue with MSSQL
