Hello,
I am getting the error
Unexpected character encountered while parsing value B. Path '', line 0, position 0
when attempting to set up Sourcetree for Windows linked to my private repository hosted on bitbucket.org.

This is a newly built PC with a fresh install of Windows 10, and I am no longer able to work on any of my projects...
I have tried all combinations of settings here (HTTPS, SSH, username, email, account password, app password) and none of them have produced anything different.
Does anyone have any thoughts on how I can resolve this issue?
