🐛 [BUG] - Unsucessfully trying to import a new json - actual claims I have opened the app in another tab (which I don't)

Description

Please bare with me, this is my first bug report/issue on GitHub.

I just wanted to import a new json, created with https://json-exporter-for-ynab.netlify.app/ to migrate from nYNAB to Actual. On importing I get the following screen:

However, no other tab is open. Broswer is Firefox, Actual on App: v24.12.0 | Server: v24.12.0.

Would you be able to provide a JSON file to reproduce with please? I don't have an nYNAB account to generate one with
