"Duplicate entry" error when upgrading MariaDB 10.6 to 11.4

I was trying to upgrade my local development environment (Ubuntu 22.04 WSL) from MariaDB 10.6 to 11.4. After updating the APT repo file, I run and apt update, which updated the server version. However, upon running mariadb-upgrade, I see this error:

FATAL ERROR: Upgrade failed

I do not understand how it is possible that there are duplicate functions, nor how to solve the problem. Since this is just a development environment, I simply tried dropping the database, but the error persists. Maybe the new version performs some checks that the old one didn't; but, how can I check for similar inconsistencies before running mariadb-upgrade in order to get a smooth update?
