I wonder if anyone here has an answer or solution to this issue.
It has been discussed for years on Google's Help Forum but they failed to have a solution until now.
It crashes when you navigate down through few levels of the directory to save a file, or choose a file to upload.
My current practice:
If I wanna download a file, I always save it to my desktop (requires 1 click on the Desktop button on the left panel).
If I wanna upload a file, I'll put the file on desktop, and select from there (same 1 click action)
I've been doing so for months and it never crash.
But whenever I try to navigate further than 2-3 level down, it crashes expectedly.
