erreror: Experiment not uploading to Pavlovia

Hi there,
I’m trying to upload an experiment to Pavlovia and I’m constantly given the same error:


re.wxAssertionError: C++ assertion “IsModal()” failed at …\src\msw\dialog.cpp(197) in wxDialog::EndModal(): EndModal() called for non modal dialog
The above exception was the direct cause of the following exception:
SystemError: <class ‘wx._core.ChildFocusEvent’> returned a result with an error set

Any idea what this might be? The experiment runs fine otherwise. Thank you!
