AskPass.exe error

I keep getting error with AskPass.exe, usually at least three times per day. The error is basically just a popup windows, that interrupts my work, even while in meetings. When one of the AskPass.exe errors happen, usually there are several more in quick succession.

This issue is pretty well documented in this thread, as other users experience this as well.

Unfortunately, the fixes proposed in this thread did not work.

Though I really like Sourcetree's UI, this issue is seriously making me consider switching myself and my team to another app, as my colleagues are having this error as well. Please, fix it, as soon as possible.
