Fix mpv hanging on exit with lsfg-vk on linux

force-exit.lua

local utils = require 'mp.utils'

mp.register_event("shutdown", function()
    mp.msg.warn("Shutdown detected. Saving state and force killing...")

    -- 1. Manually force mpv to save the "watch later" position immediately.
    mp.command("write-watch-later-config")
    
    -- 2. Get the PID
    local pid = mp.get_property("pid")
    
    -- 3. Execute the kill command
    os.execute("kill -9 " .. pid)
end)

Put the lua script inside your mpv/scripts folder
