Can’t complete setup wizard

Hi, any help would be greatly appreciated with this.
I installed the plugin and added all the info (API Key, API Password, etc.). It says it is connected with Shopify, but I can’t complete the wizard, it hangs on the final step and displays a blank page. Earlier, it didn’t even let me get to the last step (it hung on the second step if I remember correctly), but after a while it let me proceed. But now I can’t complete the setup and I can’t even skip the setup because it won’t let me go into the settings.

Thank you
