I'm seeing this under (correction: v0.22.701) on macOS. I will try v0.22.702.

[matthewberryman]

Confirmed, fixed in v0.22.702 on macOS

@matthewberryman thanks, when you say it was fixed in .702 - did you get your profile back or did it start with :gulp: ...a new profile?

[bsclifton]

Should have been fixed with 1b312a2

[matthewberryman]

@petemill Since I tried blowing away the user data folder anyway to get .701 working I decided to blow it away myself before installing .702. To test to see if .701 -> .702 keeps the user profile I then first started in .702 (since with the bug I can't make any changes in .701), added a bookmark to the bookmark toolbar, reverted to .701, saw it was still there, then swapped back to .702 and it was still there.
