I have the same issue too with the asset pack but I found the solution by making a new one from Google and I make the cube by my self.

Hi DreamLZ,
So can you explain me, what exactly you changed so it works now? I also downloaded my own blocks, because the original ones aren't available anymore. Still I get the following error:
My blocks look the following:
Can you help me and tell me, what I could try changing.
Thanks a lot!
Here I made all the cubes from yours.
Btw I found now the solution. If you have the same error as I had, do the following:
1.) Click on the extension "Tetris"
2.) Deactive there the property "Enable music" and set None for Background music. Now it works for me

I just finished making a tetris game. When I tested it, the blocks won't show up and it show this error.
you already get your answer in the error message:
Add a CreateRenderer block, maybe in Screen.Initialize event.
===edit===
I just realized you already have this block in startgame procedure, try to move it to Screen.Initialize event.
You can see other users with a similar error have solved it disabling the music:
I'll soon come up with an update that fixes these errors.
