Pycharm error code Process finished with exit code -1073741819 (0xC0000005)

I am trying to put multiple relatively large CSVs into a Df -- I am getting the error Process finished with exit code -1073741819 (0xC0000005) instead of it printing out my new DF. It makes it through the forloop ok but can't go any further.

I thought it was a memory error at first so I increased the memory heap in pycharm to 6gb. after that, I realized I was running 32bit python3 so I switched to 64bit python. I had a few issues in my pip environment so I switched to a conda environment. This is where I am at. Any advice?

The full terminal output looks like this:
