Zonal statistics as table gives unexpected error 99999 no matter what I do

[HopeHauptman]

I am using Arc GIS Pro 2.8.2 and using the Zonal Statistics as Table tool to calculate majority area and I get error code 99999. I the "raster" was originally a polygon that I converted to a rater to run the tool. I then exported the new raster and saved it as a .tiff - could this be the reason why I cant run Zonal Stats tool?  If not, what is the most common reason for this type of error?

can't make out what your screen grab has to do with zonal statistics as table, but here are the requirements for it

what is your zone raster and value raster?

What extension are you putting on the end of your output. I suggest .dbf.
