What were you doing last time you managed to be on the server? (if you have never joined, say so)
I will be flying/walking through a certain chunk or something and it will crash the launcher. This has happened 6 times within the last two days.

I have experienced this the past few days at random times

Do you have coordinates for the chunk where it happens? If you can get into the chunk and it's part of your base I would recommend you try to break all blocks from the fairy lights mod in the area.
