I simply can't get CMakePresets.json to work.

• OS Version: 10.0.19041 N/A Build 19041
• vscode: 1.74.2
• CMake Tools: v1.12.27
• gcc.exe (Rev6, Built by MSYS2 project) 12.2.0
• cmake version 3.25.1

Besieds that I tested several other configurations e.g. with "Buildtools for Visual Studio", fresh vscode installations and different Laptops among other things. I'm lost. Vscode keeps telling me

Unable to load schema from 'cmake-tools-schema:/schemas/CMakePresets-v4-schema.json': cannot open cmake-tools-schema:/schemas/CMakePresets-v4-schema.json. Detail: Unable to resolve resource cmake-tools-schema:/schemas/CMakePresets-v4-schema.json.(768)

Every time I open up CMakePresets.json.

Sorry that you're having trouble with the schema. We've seen reports of this before (#2587) but haven't been able to get it under a debugger. VS Code owns the schema loading behavior and we've seen this issue come and go. Sometimes reinstalling the extension will fix it. It breaks IntelliSense for CMakePresets.json, but shouldn't stop you from using the presets otherwise.

Perhaps this helps: If the CMakePresets.json is already open in the project when I start vscode the error occurs. In this case it does also not help to close the file and open it again.
If the CMakePresets.json file is not open in the project if I start vscode, I have no problem with the schema.

As a workaraound: Close the CMakePresets.json file in vscode; terminate vscode; start it again and open CMakePresets.json again. (NOTE: This works for my installation).
