Unintelligible error when compiling a sketch

I have been working on this APP for a long time and for the first time I get an error when compiling and I can't figure out what it is.
Is there anyone who can help me or give me a light?
Thank you very much!!!

That 92 seconds for DX compile time might be a hint.

Export the .aia source (a good idea regardless), and try to build on the higher capacity server
code.appinventor.mit.edu

Consider ways to reduce your block count using procedures, tables, and generic (Any) coding.
