Help with TSSEM Problem encountered

Dear Forum (Mike),

I have been working on a TSSEM using R and encountering the error below, which I do not know how to address. I would be grateful if you could help me proceed with your suggestions and diagnosis. I have attached the data and R codes for your perusal. 

Thank you so much for your help in advance.

Regards,

Kwabena.
