OpenBBTerminal: [Bug] slash issue

Describe the bug A “bad” load from the econometrics menu will crash the terminal. “Bad” loads have included so far: not giving an alias along with the filename, and setting the filename directly without using the auto-complete feature (which is dope, ty.)

To Reproduce from the terminal, enter the econometrics menu and try to explicitly load a filepath (i used one i just stored from FRED data) - load -f /home/<user>/code/OpenBBTerminal/exports/icsa-test.csv with or without an alias it fails, load: error: argument -f/--file: expected at least one argument which it not accurate, as it was given an argument.

Screenshots

Desktop (please complete the following information):

• OS: (Host) Mac OS X 12.2.1 running Parallels running (Guest) Ubuntu 20.04.2 ARM64
• Python version = 3.8.13

Additional context Should be easy to reproduce, hmu in Discord otherwise, happy to help troubleshoot.
