Initellisense infinite loading

[SpaghettiC0des]

Type: Bug

Suddenly happened after an upgrade.

Initializing JS/TS language features takes forever and it will hide for a split second then restart the loading process.

VS Code version: Code 1.74.3 (97dec172d3256f8ca4bfb2143f3f76b503ca0534, 2023-01-09T17:05:47.808Z)

Does this reproduce in the latest VS Code insiders build with all extensions disabled?

@karlmarxlopez I had this same error, very frustrating. Eventually I found a fix:

1. I manually ran tsc --build --verbose which gave me an out of memory error
2. I re-ran the command with 8GB of extra heap size. This time it was able to complete and showed me some syntax errors in files which were not shown before (some of them were in global locations like Typescript AppData)
3. I excluded these problematic files from compilation in tsconfig.json

After this I no longer experienced the intellisense infinite loading.

I believe this is ultimately a bug in Typescript, rather than VSCode, however -- These typescript build errors/OOM crash were never reported in the VSCode Typescript Language Server output even when I turned on verbose logging in the VSCode settings. Also, they never showed up when I ran my regular build (through an NPM script + Vite) which continued running fine the whole time.

HTH 👍

Closing as it sounds like the original issue has been resolved by reconfiguring the project
