There isn’t a lot of actionable info for others to help out here.
- What’s your OS?
- Is this on a specific device or all devices? (if you use multiples ones)
- What community plugins are installed and enabled in your main vault?
- Does it happen when only opening the Sandbox vault?
- Did you follow the troubleshooting guide (linked in the template)?
Things like that could help. The more info you can share the better.
FWIW, I’ve never seen anything like this on macOS or Windows, and I’ve been using the Obsidian 1.13.x beta from it came out.
