Parser failed to parse input completely

Hi I’m getting this error message when I run proven models in stan

I’m new to stan only started last week. Stan seems to parse sometimes and not others. I’ve reinstalled the package in rstudio and updated R and all packages.

PARSER FAILED TO PARSE INPUT COMPLETELY
STOPPED AT LINE 1:

Error in stanc(file = file, model_code = model_code, model_name = model_name, :
failed to parse Stan model ‘stan-3a447415ac3’ due to the above error.
Error in stanc(file = file, model_code = model_code, model_name = model_name, :
failed to parse Stan model ‘stan-3a447415ac3’ due to the above error.

Any help appreciated.

Can you post some model code that reproduces the issue for you?

Apologies, here you go
