Yeah, this has to do with them phasing out the old extensions. They are trying to shift over to web extensions completely. It's not quite done yet though.
i installed the new version (while retaining the old version 60.8) on my mac, but none of the accounts / settings / etc. have been transferred over. Trying to figure out how to export and import into new version but have not found out how so far
I upgraded from 60.8 to 68 on Windows and it works fine thus far.

It probably picked the wrong profile. Start with -P switch and pick your default profile. All better?
