i asked gemini to explain the traces and this is his answer:

Execution Trace

    Render Thread [7426] triggers <clinit> for net.earthcomputer.clientcommands.util.MappingsHelper.

    Static initializer invokes HttpClient.close() via lambda$static$0.

    Render Thread enters TIMED_WAITING at jdk.internal.net.http.HttpClientImpl.awaitTermination (line 605).

    HttpClient-2-SelectorManager [8321] remains in native epoll_wait (RUNNABLE).

The Deadlock The Render Thread holds the Class Initialization Lock for MappingsHelper. It is blocking to wait for the SelectorManager thread to terminate. If SelectorManager requires any synchronization or class resolution involving MappingsHelper to complete its shutdown, a circular dependency occurs.
