bug: Nvim0.10.0 crash / neovim was disconnected

[HappyRustacean]

Check the following:

• I have checked the behavior after setting "vscode-neovim.neovimClean" in VSCode settings.
• I have read the vscode-neovim docs.
• I have searched existing issues.

Neovim version (nvim -v)

NVIM v0.10.0 Build type: Release LuaJIT 2.1.1713773202

Operating system/version

Mac Os X 14.5 (23F79)

Describe the bug

In the latest version v1.12.0, Neovim on macOS automatically exits after switching multiple VSCode tabs, causing plugins to disconnect.

Steps To Reproduce

1. Open VSCode on macOS with the Neovim extension.
2. Open multiple tabs within VSCode and maybe some splitted window.
3. Switch between the tabs multiple times.

How to Solve

downgrade nvim version to

NVIM v0.9.5
Build type: Release
LuaJIT 2.1.1713773202

So it's actually a bug of nvim0.10?

Are you sure you didn't use any plugins?

[bomut]

Just adding my 5ct: I can confirm, after downgrading neovim from 0.10.0 to 0.9.5 the issue is resolved.

@bomut With "neovimClean" ?

[bomut]

No, I downgraded neovim via homebrew (following this guide using this bottle; yes, it's a bit cumbersome).

Any kind of logs would be very helpful. I don't have a Mac to debug with (maybe someone else does), but we may be able to narrow something down. You can find instructions on how to gather them here

I have the same issue

OS

macOS 14.5 (23F79)

Neovim version

NVIM v0.10.0
Build type: Release
LuaJIT 2.1.1713773202

Log

I've attached the logs that were captured during the issue. The logs are quite long, and the most relevant information is probably towards the end. However, I'm including the entire log file just to be thorough.

@HappyRustacean @bomut What I mean is whether any plugins were used. Some plugins might cause Nvim 0.10 to crash, for example, by using incorrect FFI.

[xiyaowong]

Confirmed in Windows 11.

[JohnEricson]

Yes, I got the same problem in Windows 11. Downgrading Neovim to version 0.9.5 solved it again.

[cayossarian]

I believe I have the same issue (on macos), the log message I get is "MainController: Neovim was disconnected". I also am running neovim 0.10 but have another work around.

Rather than dowgrading neovim I see that downgrading the vscode neovim plugin to 1.11.5 also resolves this issue. Every version after 1.11.5 cause this disconnect/crash.

The log is filled with these messages:
ERR 2024-05-29T14:30:32.063 nvim.98485.0 chan_close_with_error:561: RPC: ch 1 (type=2) returned a response with an unknown request id 0. Ensure the client is properly synchronized

Use Nvim v0.10.1 or the nightly version.

[UncleGoogle]

Nightly version v0.11.0-dev-85+g93c55c238 still disconnects for me
wrong issue. Mine is ubuntu on WSL

Thanks, this helped!

For anyone else running into this on a mac.

brew uninstall neovim
wget https://raw.githubusercontent.com/Homebrew/homebrew-core/63aa44faba5b5274a1a7579510cd5a570a2cca5f/Formula/n/neovim.rb
brew install -s neovim.rb

using neovim on mac, switched to nightly and seems much better.

@patleeman anyone using homebrew to install neovim on mac ;)

mise use -g neovim@nightly

brew install -s neovim.rb

This command appears to install nvim 0.9.5. I just installed it and hope it resolves the issue.
