"there is already a sclang session running" nvim keeps hanging

[dotrosedotnet]

t was working flawlessly, and now suddenly it's telling me there is already a sclang session running, remove it first, then retry

This is in tmux, when I run :SClangStart

this happens even on fresh reboots, so there is definitely no sclang session running.

running :SClangHardstop or :SClangKill just hangs. I can get back into nvim with ctrl+c

I'm running nixos 21.05 on kernel 5.14.14 on an amd cpu/gpu. everything is updated.

Thank you for understanding, I've never written an issue on github before, so I'm quite sure I'm not doing this exactly right. Please let me know other information can help! This is super important to me.
