I cannot reproduce. I was able to clone, search for x86 and navigate the multibuffer with 8130 results without incident.

Do you have any Zed Extensions installed or other relevant settings (languages, etc) which might be impacting this? Can you try removing your Zed Extensions and seeing if it still crashes? And if not, install them back one by one to come up with reproduction steps? If that doesn't work can you backup your Zed settings and try with an empty settings.json {} in case that helps?

[LouisBrunner]

I have a bunch of extensions, I tried uninstalling them one-by-one, starting with C# and it stopped crashing right away. After reinstalling it, it is still not crashing.

So I cannot reproduce it anymore either.

[0x2CA]

In today's day I also suddenly crashed at the zed project, and I think the language extensions may have crashed zed

I'm guessing it's because the internet downloaded half of the lsp, then zed ran it and it crashed
