It looks like you accidentally reopened Citra before uploading the log. The log gets cleared every time you open Citra. Have the log folder open in the background first before closing Citra then immediately upload a new log.
Luigi’s Mansion 2 has quite a lot of issues. On my end, if I try to run the game on my iGPU it will take ~5min before it can reach the title screen but on a GTX 1070 I don’t have to wait that long.
You can try underclock Citra to about 25% in the system tab.
