Crash on startup after updating my system: "Panic: runtime error: invalid memory address or nil pointer dereference"

[Invertisment]

Describe the problem

I enter my NVIM and it starts the LSP server.

Almost immediately the LSP server crashes with this message in the editor:

Client 1 quit with exit code 2 and signal 0

Then I get this message in the LSP log:

To reproduce

It's enough to start my editor with .ino file.

clangd version 18.1.8

NVIM v0.9.5 (I had to downgrade from 10.1 because of this bug: #186)

Expected behavior

No crash.

Arduino Language Server version

0.7.6

Arduino CLI version

1.0.3-arch Commit: 8b6ad258e88581a9e77b2eede65aeeeeb265008c

Operating system

Linux

Operating system version

6.9.12-1-MANJARO

Additional context

Note: If I upgrade to the @latest unstable version then it doesn't crash (go install github.com/arduino/arduino-language-server@latest)

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the latest version
• My report contains all necessary details

@Invertisment 👋 thank you for taking the time to open the issue. The reason is that the latest stable doesn't target the arduino-cli v1.0.0 yet. For this reason, I suggest installing the LSP with the latest tag go install github.com/arduino/arduino-language-server@latest.
This will be needed until we release a new version, that will target the new v1 version of the arduino-cli.
