    Hello! a similar problem, only the error "Wintermute::Geometry::Verify" does not appear in the logs, and the process does not stop even after the remark is stopped. After that, you can close Unity only through the Windows Task Manager.
    The same situation occurs when MESH COMPRESSION is disabled.
