I tried reproducing this on core@13.0.1 using a clean profile and tested project/workspace switching, sidebar filtering, project/workspace dropdowns, and sync-related menus, but I could not trigger the crash.

Could you share the exact action that causes the error, or whether it happens only with a particular project/workspace? If possible, a sanitised export or more details about the project structure/sync state would help.

I am seeing a very similar error. It happens immediately after logging in or opening the app. I briefly see a working screen, and then it is replaced with the error. I have tried restarting, logging out and logging back in, and restarting my computer. Other folks on my team are not having the problem when logging in with the same account.

I moved the entire ~/Library/Application Support/Insomnia folder to Insomnia_backup and then restarted the application, and that fixed the issue. Fortunately, we use cloud for queries etc, so it was ok to lose local data.

[Congo2005]

losing local data isnt an option for us, so this is still an issue

[jakem-PAR]

I am experiencing this same issue.

I am experiencing the same issue, the app is unusable.

Not sure if helpful context, but before I saw the issue for the first time I had deleted one or two empty Projects from the sidebar on the left hand side of the screen.
