Sourcetree stopped working

[sergio_vasconcelos]

Hi, 

My source tree just won't launch, without any modification on my end (windows 10).

Already tried: 

•  Deleting every app data combinations of folders possible described though out this forum and others, and restarting the pc
• Uninstalling and installing again 3 times and restarting pc. 

Thanks.
