If the desktop installer crashes, the "Something went wrong" screen will show up and there is a green button on the bottom right that will allow you to restart the install. After clicking the restart button it will start a spinning animation in the button but otherwise no other updates to the UI are made. I know the install in the background worked because the failure happens again and the whoopsie dialog prompts again to report a problem. However, after the second failure the restart button continues spinning and has no updates to inform the user that the retry has failed.
The particular cause of the crash is so far unimportant. To reproduce this issue, I provided an autoinstall configuration with a late command that would cause the installation to fail:
late-commands:
- $((1/0))
but I was first made aware of this issue when encountering a real bug.
