Thanks for the report @ocavue, I can reproduce the issue. There have been some breaking changes in v6, but unfortunately, we haven't added migration instructions for this plugin yet. One of the changes is that what was previously the recommended config is now named processor. The config name was changed to make room for a recommended config that includes language capabilities, one of the newest features in ESLint, also to be documented.

To fix your config file use the processor config instead of recommended for @eslint/markdown v6.

@fasttime Thanks! That works.
