Can you reproduce this with vscode insiders https://code.visualstudio.com/insiders/

@isidorn Yes, still exists.

If you F1 > developer tools > open console
Are there some errors?
Does the code or the file system chane the test.go in any way underneath?

I seem to be having a similar issue, get the following in the console:

I think this was also the same issue in #72755

I've not been able to reproduce consistently. It seems to happen when I open an existing workspace that has open tabs, and switch to a tab for a file in that directory. If I close all the tabs in a workspace, the folder contents stop disappearing for the duration of that session.

Since i‘ve upgraded golang and all of packages, for some reason this issue has gone, just for me. Now i can't reproduce again wherever in 1.33 or insider build.

Closing then. We have similar issues which we plan to investigate next week anyways
