Language server fails to start when workspace has ephemeral directories

[dualmoon]

Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.

Summary

I believe this may be similar to #2491. I was connected to a samba share and working on some various files. I closed my Macbook and a couple days later came back to do some other work. The samba share was no longer available at this time. The Powershell extension failed to load and gave the message "timed out waiting for session file to appear". Per #2417 I tried to run:

pwsh -NoProfile -NoLogo -ExecutionPolicy Bypass -Command "$PSES_BUNDLE_PATH/PowerShellEditorServices/Start-EditorServices.ps1 -BundledModulesPath $PSES_BUNDLE_PATH -LogPath $SESSION_TEMP_PATH/logs.log -SessionDetailsPath $SESSION_TEMP_PATH/session.json -FeatureFlags @() -AdditionalModules @() -HostName 'My Client' -HostProfileId 'myclient' -HostVersion 1.0.0 -LogLevel Diagnostic"

It got partway through but then hung at "Starting server, deregistering host logger and registering shutdown listener"

I couldn't Ctrl+C the process or anything, had to use another term tab to killall -9 pwsh. More searching led me to #2491. Someone there mentioned something about maybe number of files in the workspace, which reminded me that I had also gotten an error about the samba mount being unavailable. I closed the workspace entirely, then closed and reopened Code again and Powershell's lang server loaded without issue.

Obviously this is a super minor edge case but I wanted to mention it just in case there was some error checking that could be added. I'm not entirely sure why this fixed it but it did! I wouldn't think the lang server would care about workspaces or files generally when initializing the lang server but apparently it does!

Please let me know if I can provide any additional info. Obviously I'm fine now but I just want to help where I can :)

Hey, thanks for the info, but unfortunately this seems like it'll be nigh-impossible to reproduce adequately enough to fix, and as you said, it's quite the edge case. I'm going to mark this as resolved (won't fix) if you don't mind. The "numerous files in workspace" issue #3307 is still open and pending investigation, which if solved would potentially solve this issue too.
