Alright, I’ve replicated the issue on my computer using the sandbox vault (mostly: loss of all secondary windows, rather than all tabs in all windows).
- First, I tried it with a local copy of the sandbox repo. This enables workspace.json saving to disk.
- Second, I also tried it with the Obsidian built-in “Open sandbox vault”, and found workspace.json in
C:\Users\%user%\AppData\Roaming\obsidian\Obsidian Sandbox\.obsidian
In both cases, I could see that workspace.json shrunk in size upon closing Obsidian. Not to zero (so slightly different from my main vault problem), but still losing all secondary windows.
- When I used the local copy of the sandbox repo, reopening Obsidian confirmed that the main window tabs remained, but the secondary window was lost.
- When I used the built-in “Open sandbox vault”, the sandbox reset upon reopening.
Here are screen recordings for both scenarios:
