Error In Colliding Block When Entering Dimension

I had a previous topic on this, but It got closed or something or just no one responded to it. Anyway, in Mcreator's Pre-release for the new 2020.1 version, the Dimensions still have this bug where when entering the portal, it doesn't send me anywhere or do anything. In mcreator's gradle log, it shows an error that can be seen right here in this pastebin when I try to enter any dimension: https://pastebin.com/nEvBRvZB
