Filesystem Kernel Panics; Help with Diagnosis?

I've been getting frequent kernel panics today; seemingly related to the filesystem. I was doing some work involving Google Drive (running the Drive File Stream helper), and Dropbox (running with Finder integration).

Panics seemed to first be caused by the iDrive online backup system, so I've disabled and uninstalled that. The last couple were caused by mdworker, but the only common thread seems to be that filesystem kexts are the most recent before the crash.

I'll paste a panic report and Etrecheck report below; I'd appreciate any help with diagnosis.
