My credit card just got pinged again this morning and reminded me that i tried to ignore these bugs over the holidays but i really really need this crash fixed. i just updated my neovim config in wsl (nh os build) and it crashed again, which requires me to close most of my windows and restart most of my apps to get komorebi working again. i started my nixos-on-wsl journey by using your setup, so i feel like you should be familiar with my pain 😆

lmk if there's more logs i need to provide or debugging steps i need to do

I've been looking into these kinds of inexplicable crashes for a while and finally managed to catch a dump of one which I analyzed to find a use-after-free bug. I just pushed a commit on the master branch for anyone who wants to try it out (also pinged the @Testers group in the Discord)
