We encountered an error trying to save your calculated field. Please try creating it again

Hi I got this error within an analysis for all the formulas.
I did simple SUM, now() function, etc, all of them returns this error.
I tried other analysis, work all fine.
Can anyone help with it?
Below is the error msg
