Problem to synch

I am a bit desperate. I have a perfectly functional task and I already was able to synch with Pavlovia, and all of a sudden, I get errors like this while trying to synch (I don’t code):

Traceback (most recent call last):
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\app\pavlovia_ui\”, line 364, in onSyncButton
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\projects\”, line 651, in sync
status = self.pull(infoStream=infoStream)
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\projects\”, line 694, in pull
raise e

raise GitCommandError(command, status, stderr_value, stdout_value)
git.exc.GitCommandError: Cmd(‘C:\Program Files\PsychoPy3\MinGit\cmd\git.exe’) failed due to: exit code(128)
cmdline: C:\Program Files\PsychoPy3\MinGit\cmd\git.exe pull master
stderr: 'warning: no common commits

  • branch master -> FETCH_HEAD
    fatal: refusing to merge unrelated histories’

Does anyone have encountered something like this?
