Bug: Loading drive size on home page sometimes fails

### Description

I switched to the home page from another folder via the sidebar, this is the first time after many home page loads

### Steps To Reproduce

1. Open folder
2. Switch to home page via sidebar
3. See a drive show `Unknown` for size information before crash

### Files Version

4.2.8.0

### Windows Version

10.0.26200.9168

### User ID

670e1391-905a-4fe8-a9da-a22f01a4676c

### Log File

[debug.log](https://github.com/user-attachments/files/31159965/debug.log)

Start by reproducing the Windows 10 issue with the listed steps, then inspect debug.log around the home-page transition, the drive showing Unknown size, and the crash. Trace the drive-size loading entry point from that evidence; done means switching from another folder to Home no longer shows Unknown or crashes.
