Just a meta to keep track of all issues related to blank devtools on startup, most likely linked to hanging / blocked processes.
We have had many reports in the last months, but the bugs are spread and not linked to each other.

Is there a way we can make it more obvious what might be happening with logging or something?

A discussion is ongoing in bug 1918267 with reason why this happens and I'll attempt to fix these issues there.

:ochameau is adding some logs in his patches for Bug 1918267, should help already to identifies the processes slowing down the DevTools opening. If the issue persists after this patch lands, we should display something directly in the toolbox I think.
