General problems with my app (Creator bugs?)

I’m currently making an app in Kodular and I already worked 2 weeks on it, but today everything began to go wrong. First of all the creator wouldn’t copy a page and just created bugged ones that couldn’t be opened. Now when I try to open my home page it also crashes. Some screenshots are below (I think). I really don’t know where this could come from, as I have used all the extentions without problems before.


If you need any more details, please just tell me and I’ll do my best. Thanks in advance!
