Unable to resolve resource cmake-tools-schema:/schemas/CMakePresets-v3-schema.json in trusted workspace

[1100101]

Brief Issue Summary

I am unable to verify the content of my CMakePresets.json/CMakeUserPresets.json against the JSON schema that comes with the extension, because apparently the extension is not able to open the schema resource:

[{
	"resource": "/d:/CMakePresets.json",
	"owner": "_generated_diagnostic_collection_name_#0",
	"code": "768",
	"severity": 4,
	"message": "Unable to load schema from 'cmake-tools-schema:/schemas/CMakePresets-v3-schema.json': cannot open cmake-tools-schema:/schemas/CMakePresets-v3-schema.json. Detail: Unable to resolve resource cmake-tools-schema:/schemas/CMakePresets-v3-schema.json.",
	"startLineNumber": 1,
	"startColumn": 1,
	"endLineNumber": 1,
	"endColumn": 2
}]

This is a with a cleanly installed version of VS Code, with default configuration (no custom settings whatsoever).

When I Open a CMakePresets.json with the extension installed, at first no error is shown because the application is in "Restricted mode" (the workspace hasn't been trusted yet).
As soon as I trust the workspace, the schema error appears.

Typing silly values for some of the CMake JSON variables has no effet, the file is not validated against the schema.

We've been seeing spurious reports of schemas not being found (I've experienced it before as well, but not consistently for us to be able to debug it yet). #2135 refers to another case of this, but with a different file (cmake-variants.yaml). What's weird in your report is that you say that cmake.logDiagnostics is not found which might point to a corrupted installation of the extension. Perhaps uninstalling and reinstalling it might help with that.

Is it possible that the extension only works correctly if I open a folder (with CMakePresets.json) in VS Code?
When I do that, I don't get any errors, and the schema seems to be handled correctly.
If I open just the CMakePresets.json, the error shows up.

Yes, the extension does not activate automatically in that case. I'm surprised that VS Code would try to load our schema without loading our extension though. This may be a VS Code issue.
