Start in main.kt at MainKt$c.invokeSuspend, using the String.substring stack trace as the entry point. Reproduce by applying a backup file on the desktop app, then inspect the restore and restart path for the empty string that causes the exception. Done means the restored app launches successfully on Windows and Linux Mint.
