This error does not depend on the launcher. By default, all single worlds (open LAN) work with online-mode=true, so your offline account cannot be successfully verified on Microsoft authorization servers. You need to run local server with next minecraft softwares: vanilla, paper, fabric, forge or else loader.

You can get information about how run your local server with few click and terminal commands via ChatGPT or else LLM models. If you can't use LLM, use search engine like Yandex, Google or something else.
