Which version of the Recorder are you using? You can check via the “Manage extension” menu option.
I just tried with v0.6.2 and Chromium v110.0.5481.177, and was able to record a session, and download the generated HAR without issues. I also see it in the “Recording history”.
I am using Chromium instead of Chrome, a slightly older version, and running on Linux amd64 instead of macOS (I’m assuming) ARM, but I doubt that would cause this. Maybe there’s an issue with the new Chrome version?
I’ll inform our internal team who works on the extension to see if they can help out.
In the meantime, can you try the extension on Firefox, or from another machine? Just to rule out whether it’s an issue with Chrome or your system.
I had a chat with the extension team, and they’re not able to reproduce this either. It would be very difficult to know what happened in this case, since we would need to test with your exact system setup, including other extensions.
Since the workaround is just restarting the browser after the first installation, we suggest doing that if someone else runs into this. If it becomes a larger issue, we’ll need more information in order to reproduce it.
