I’ve recently seen a bunch of users experiencing a problem with gimkit creative being frozen.
Your not alone I myself have a glitch that freezes my screen when I add something.
For now I say Email gimkit. Again I don’t think this is a problem on your end this is similiar for me.
I think your issue is kinda like this post.
Hopefully gimkit resolves this. I’m not sure if this for you or just me but the bug doesn’t apply for maps that are platformer.
