Steps to Reproduce:
I am using it for salesforce development and install salesforce extension pack
I am getting error from Aura Language server
[Error - 11:36:05 AM] Starting client failed
Error: spawn C:\Users.....\Microsoft VS Code\Code.exe ENOENT
at Process.ChildProcess._handle.onexit (internal/child_process.js:264:19)
at onErrorNT (internal/child_process.js:456:16)
at processTicksAndRejections (internal/process/task_queues.js:84:9)
*Tried reinstalling extension it failed shows same error
and reinstalled vscode also still same.
Does this issue occur when all extensions are disabled?: Yes/No

I'm getting errors too, not sure this is the same problem:

Fix will be released tomorrow
This should be addressed with our latest release (47.10.0).
Updated it, Still problem persists for me.
I also tried to disable "Aura Components"
then there was no error but once enabled or updated or installed older version of extension
below error is there:

@neelgo Just to confirm I'm understanding correctly, you're still seeing the "Indexing Lightning Components" message with the latest version of the extensions (47.10.0)?
I am seeing the same message that i have posted 3 days before and with initial question.

Same problem all day. First time trying to use VSCode with SFDX

I updated to most recent version 47.17.1 and received this error. I tried the above troubleshooting steps of downgrading and uninstalling extension to no avail.
Any help would be greatly appreciated, thanks in advance.
