Hello Christian Marquardt,

MySQL Workbench 8.0.40 was originally released on October 15, 2024, without the mysql_native_password authentication plugin. The issue was addressed and Workbench 8.0.40 was re-released with the fix on October 31, 2024. If you installed the original release, then uninstall it before installing the newer version. Please see - https://dev.mysql.com/doc/relnotes/workbench/en/news-8-0-40.html

regards,
Umesh
