Issue comments

In most cases, this is caused if MCreator is not able to access the internet. Make sure you don't have firewalls or antiviruses blocking MCreator, uninstall it and install again.

If the error persists, wait a bit as Minecraft Forge servers might be overloaded at the moment and then reinstall again.

I don't have other ideas what to do as this error has to do with something blocking MCreator in most cases. I suggest you search a bit on our website for Expected BEGIN_OBJECT but was STRING at line 1 column 1 as many users had this error and fixed it and you might find their solutions useful as a guide on what else to do/try.
