Classification for this project is only available in the browser error

[TGAlgar]

It is a really pity to have this issue in this moment. Working with children (10-12 years) and everything worked fine.
Some features were removed from ML4K and using KEY it worked but today I thing major changes have been done and I get this error:

Classification for this project is only available in the browser error

I received same data I had sent but I don't get the classification I am requesting from the model.

I think this project is unsupported but I would appreciate if there is some workaround to fix it.
