An unhandled internal error in Psychopy

Hi, I designed an experiment that runs fine on my macBook. But every time i want to upload it to Pavlovia there is this message appeared:

Traceback (most recent call last):
File “/Applications/”, line 507, in
File “/Applications/”, line 476, in _run
File “/Applications/”, line 104, in
File “/Applications/”, line 100, in main
File “/Applications/”, line 28, in start_app
File “/Applications/”, line 226, in init
File “/Applications/”, line 252, in onInit
File “/Applications/”, line 503, in SetTextPosition
RuntimeError: wrapped C/C++ object of type AdvancedSplash has been deleted

Is there anything wrong with my Psychopy 3? Can I still upload my experiment now?
Any help appreciated!
