Hey, thanks for the detailed report. Having the Request ID and a screenshot is really helpful.
This is a known issue with chat context where the agent gets confused and may switch to a different language or topic. We’ve seen similar reports from other users here: Extreme topic change upon return to agent conversation and here: !Reproducable! - Context pollution from a completely foreign project.
Your version (2.5.26, build from Feb 26) is older than the fix that shipped on March 9. Please update Cursor via Help > Check for Updates. That should help.
If it happens again after updating, please start a new chat (that’s the current workaround) and post back here. The team is aware, and your report helps us prioritize it.
