DisableOperaPackageAutoUpdate seemed to be removed.

No error message. Simply won't start. The icon will appears three times and no trace of process ids in the activity monitor...

Chrome had a similar problem a few weeks back, I guess it is not Opera's turn. No crash or other error info, no record on console, simply doesn't do anything when starting up.

I tried to visit https://material.angularjs.org/ today using Opera and got certificate is revoked warning and cannot move forward. How do I go ahead and visit the website anyways like I could on Chrome?

Same, did a roll back.

Yeah I did that. It was a very strange bug.

"WAS?" Did deleting "Local State" fix it?
I'm still not convinced this is a bug. Have you checked your preference region selection?

I just noticed that this says it's my first post. How that is possible is beyond me. I've posted more than 22,000 comments to the Opera forum in the last decade and half (maybe longer).

I went into the file and replace CN with US somewhere I forgot. I think I manually switched it to the US. Another computer the location was registered at JP. I think there should be a menu option to allow users to change it.

You could delete the file "Local State" and see if Opera determines your location correctly this time. Altenatively you could edit the file in a text editor to the correct location.
