They suggest that it happens during update installation, which makes sense considering the command that's failing is part of the updater/installer.

Desktop (please complete the following information):

• windows only
• happens every desktop release
• first reports came from v3.103.3, so it's probably something we introduced with that version or the one following (with the failing signature extraction)
• we had about ~160 reports of this since November 15

Test Notes

• update from affected version to fixed version worked on mac, windows, linux
• update from fixed version to fixed version worked on mac, windows, linux
