Issue:

Whenever a workspace is opened, git plugin actions are not working from the command palette and plugins/runtime info are not displayed in the side panel. Same behavior observed on Java Maven or Cake PHP workspaces. Refresh (browser via F5 key) does not help.

The workspace shows a lot of errors and one or two FIPS errors.

Will add customer logs in a private comment.

But as per the mail thread, here is some more information:

There are some errors in the log about vscode-git, and it seems they are
related to vscode-git trying to dispose a non-existent connection. The
cloning failure could be related to this.

As for the repository missing in the Web UI, it could be related to the
Theia issues. If Theia isn't working in a FIPS-enabled
environment then it's likely the built-in plugins won't be working
properly either

Please note that  FIPS is supported on OCP 4.3
