TabularData - OSError

Hi, I previously build a Tabular model without any issues, however, I added 2 new columns and now whenever I try to construct my data bunch I get the following error: OSError: [Errno 36] File name too long

There are actually a lot of errors starting with File “/opt/conda/lib/python3.7/multiprocessing/”, line 236, in _feed
obj = _ForkingPickler.dumps(obj)

Any ideas? Thanks!
