Processing on ubuntu cannot access external hard drive

I recently installed the latest version of Pop OS, which is a Linux distro based off of Ubuntu. When I installed processing and went to look for a project file on an external disk, it did not show the complete filesystem. It did not list external drives, and it strangely mislabeled my 256 GB main drive as 8 GB.
Does anyone know of a way to fix this?

I fixed it! Heres how to do it:
Do not install processing from the pop shop.
Install it from the processing website.
