Solution explorer displaying non-existant files with guid names

[Numpsy]

Describe the bug

The solution explorer in the latest versions seems to be displaying guids like these as part of the file tree, e.g.

which don't exist if I try to select them.

Are those supposed to be there?
They aren't there in version 7.22.0 for comparison

Machine info

this is almost certainly a side effect of moving to the new solution parser from vs-solutionpersistence instead of our own homegrown parser. We likely need to do more filtering in FSAC in the workspaceload/workspacepeek logic to filter out these noisy entries.

On closer inspection with a project at work, I get this with the latest Ionide:

compared to this for older versions:

So rather than trimming the guids, I wonder if it needs to rearrange things so that the projects appear in the places that are currently guids?

Also, it looks like 'not project' items like build.fsx aren't displayed
