gvfs upgrade crash

GVFS Version: 1.0.18297.1

C:\Users\corepkg>gvfs upgrade --confirm
Checking for GVFS upgrades...Succeeded
New GVFS version 1.0.19060.1 available in ring Slow
Launching upgrade tool...
 
Installer launched in a new window. Do not run any git or gvfs commands until the installer has completed.

And then it crashes in the new window:

Start by reproducing gvfs upgrade --confirm with the versions and Slow ring shown in the report. Read GVFS.Common.ProductUpgrader.TryDownloadAsset and the surrounding upgrade flow in TryDownloadNewestVersion; done means the upgrade no longer crashes with a NullReferenceException and completes successfully.
