Unable to dump stack trace: FileNotFound

I think this may be related to having an @import that results in a file not found, will update with more info if I find a more specific repro.

[nektro]

what was the code that caused this to happen?

Also ran into this problem (or a similar problem). Here is a repo which reliably crashes ZLS for me on Windows (haven't tested on other systems): https://github.com/obiwanus/zls-crash-test

In the readme there are instructions on how to reproduce the crash.

I forgot to add that I tested it in VSCode

The provided reproduction no longer crashes with latest zls (after making the necessary changes to get zig build -h to work with latest zig).
