Description
Hello, I just installed the VS code lean4 extension, but the "Lean Infoview" is blank. I am using an ARM64 build of Windows 11, but I have the x64 build of Lean installed and am able to build and run lean programs in the VS Code terminal. The "Lean documentation" works, but not the infoview.
Do you have any suggestions for how to debug this? (I am a programmer, but my expertise is in C++. I'm not familiar with React.)

Research direction
Start by reproducing the blank Lean Infoview on ARM64 Windows 11 with the x64 Lean installation, using the VS Code extension and its terminal context. Inspect the extension's available diagnostics and logs to identify why the Infoview fails to load; done means the Infoview displays normally in this setup.
