@mtrunt @mattmarcum @EWhite613 4.1.0 has been published on the chrome store, which should fix the issue. If it doesn’t, feel free to comment here and I can reopen the issue.

I noticed this after I posted the comment, but unfortunately even the nightly channel is currently quite behind due to long review queues (probably COVID-19 related). The current approves version of nightly is from May 1.

You can instead go here and download the build manually. Find the artifacts drop down and click chrome.zip. Unzip it into a folder. Go to chrome://extensions, disable the ember inspector you have now and click “Load unpacked…” and select the folder you unzipped.
