@n-takumasa I am still getting the error when I run an interactive window in vs-code

Version: 1.74.3 (Universal)
Commit: 97dec172d3256f8ca4bfb2143f3f76b503ca0534

Node.js: 16.14.2

OS: Darwin arm64 22.2.0
Sandboxed: No

I downgraded to ipython 8.1.1 as well as the latest and still get the same error.

Could it be related at all?

On my environment (Windows 10 + vscode 1.74.3 + IPython 8.8.0), the error (ERROR! Session/line number was not unique in database.) does not reproduce.
I think it is an issue with your environment.
