Terminal doesn't start

After SourceTree updated to 1.6.23 'Terminal' button doesn't work anymore.

Current directory:
C:\dev\project

Command to be executed:
"C:\WINDOWS\system32\cmd.exe" /C "C:\Users\user\AppData\Local\Atlassian\SourceTree\git_local\git-bash.bat" --cd="C:\dev\project"

Which is failed with error "The filename, directory name, or volume label syntax is incorrect." caused by --cd switch (works without it)

It's critical because some of git features are not available via GUI so please fix it ASAP.
