notebook pyspark constant errors writing more than 2 files

The data exists in the delta table in the lakehouse and it seems to display the data without issues - so I'm assuming the structure of the delta files are fine.

But it seems like a issue with data quality specifically column names with suprious characters like $ . " etc. But if it is already in the lakehouse as delta table don't understand why it can't output the data without failing. Anyway I had to clean up all the column names then it worked
