Language Server hallucinates errors

[bbrk24]

Environment

• OS and Version: I'm on Windows 11, but I'm running VS Code in WSL2 (Ubuntu 22.04).
• VS Code Version: 1.93.1
• C/C++ Extension Version: 1.22.7
• If using SSH remote, specify OS of remote machine: N/A

Bug Summary and Steps to Reproduce

Bug Summary:

This isn't consistent so I can't give a good reproduction, but sometimes when I open certain files the language server invents an issue to get mad at. As shown in the screenshot below, it's complaining about a mismatched { on line 37, character 3, but line 37 only has two characters. If I close all editors and reopen this file, there is no error; if I restarted the extension without closing the file, the error came back as soon as the extension was online.

It also said "expected a declaration" at one point with no further notes, but I didn't get a screenshot of that.

Steps to reproduce:

1. Open a file with a C++ class definition
2. Scroll down to the };
3. Observe error squiggles

Expected behavior:

No error

Configuration and Logs

I can't put it here because if I do, GitHub gives me the error

> Comment is too long (maximum is 65536 characters)

It seems to be searching the node_modules of a subdirectory for includes, which is why the log output is so long. If need be, I can upload it as a .txt file.

Other Extensions

While I do have a decent number of extensions (22 total), I don't think any of them affect C/C++ error squiggles.

@bbrk24 I think we need more repro info. This might be fixed with our pending 1.22.8 from #12175 .

[bbrk24]

Yeah, I can't reproduce this anymore (1.22.9).
