auto-imports (import suggestions) randomly stopped working

Type: Bug

A little while ago (like over a week now), I was working as I always do, and all of the auto-import suggestions for typescript just stopped working completely. I hadn't updated anything manually (my os, vscode, extensions, node modules, etc). It is possible something auto-updated somewhere behind the scenes, but I haven't been able to track it down.

Essentially no auto-imports work at all in my project anymore. I can't import from relative pathed files, workspace files, or node modules. All typescript imports, once imported work fine and are recognized, but any of the "quick fix" suggestions just don't work at all, both as I type or hovering over a missing reference. The quick fix popup does show, but the only option is my tabnine extension.

What is strange is the imports have worked once since they stopped. I did nothing out of the ordinary and they just randomly started working again. But then as quickly as they appeared, they disappeared.

I've tried all of the following:

• changing ts versions
• changing between vscode and project ts references
• changing my pnpm version
• turning on and off every one of my extensions
• changing memory and storage size limits on wsl
• trying to initialize the project in various ways (docker first, complete rebuilds, etc)
• nearly every possible setting related to ts and tsserver in the vscode settings
• nearly every possible intellisense setting I could find that might be related
• restarting vscode and ts server in various ways
• changing any settings related to docker, workspaces, or anything else that might affect my ts path lookups

The only other piece of information I have is this error in the ts logs, but I've tried tracking it down, even manually modifying the ts server code and logging things out for a couple hours, with no obvious things that stand out on why it is failing. This error appears when I try to hover over a known missing reference to have it show the imports, but then it just doesn't show them, presumably due to this error (some path parts redacted for privacy reasons).

From what I can conclude, this seems like either a timing issue withing vscode starting things up, or some internal vscode or extension thing somewhere broke behind the scenes. I'm on a wsl docker setup, so there is a lot of linking going on behind the scenes, but given I hadn't changed anything when this started happening, I'm at a complete loss on what to even look for further at this point.

Oh, and unfortunately, I haven't been able to reproduce this on any other machine, so I'm a bit stuck on that front. I'm happy to try modifying any settings suggested, I just have no idea what else to look for at this point.

Start with the reported getCodeFixes request and the Debug Failure stack in node_modules/typescript@5.4.5/lib/tsserver.js, focusing on getImmediateAliasedSymbol and the surrounding import-fix path. Reproduce the failure in the reported VS Code 1.90.0, TypeScript, WSL2, and pnpm setup if possible; done means auto-import code fixes work without the exception. No source test or minimal reproduction is named.
