The author of the OP appears to have edited it to indicate that it's just crashing, and doesn't know if it's a segfault or just a panic. It appears there is some known potential for segfaults in tree-sitter, which is a native C dependency.

I have had treesitter crashes in the past editing markdown, causing helix to segfault, but the particular bug that caused my crashes has been fixed since years.
