Hey, thanks for the report. This looks like a corrupted chat state, when a tab “breaks” and stops showing history correctly and working properly. Unfortunately, you can’t restore a broken tab, but your new tabs are working, and that’s what matters.

Workaround: keep working in a new tab. If you need context from the old chat, you can open it, review the content (at least your prompts), and copy it into the new one.
