Large Screen Recording Failed

Large Screen Recording Failed

I did a test of Recording a Google Meet on my Pixelbook and it worked well. So I then I did a screen recording of a actual 2 hour Google Meet presentation. The recording seemed to work and the counter lasted the entire time. When I hit the stop button it seemed not to respond, waited a few seconds and it seemed to stop on second click, but did not bring up the edit page. 

I searched the questions related to finding the video edit page and found the URL: 
chrome-extension://bpconcjcammlapcogcnnelfmaeghhagj/edit.html?video

This brings up my original test video, not the expected longer newer recording. 

Should assume that recording failed and is lost? Is there any other place the video is cached and might be retrieved.
