@bbildman You probably just have to wait for a fix. Or, for now, you can goto the URLs opera://settings/adBlockerLists and opera://settings/trackerBlockerLists, when adblocking and tracking are enabled, disable a list that's enabled, restart Opera and see if the crashes stop. Maybe you'll find that it's a specific list (or lists) that's the culprit.
An alternative though would be to leave Opera's adblocking and tracking protection disabled and just use uBlock Origin.
