So, as context, I'm writing some controller software in Python for a RTM3004 oscilloscope for laboratory use. I had it working just fine on my laptop (Win10) and the previous laboratory computer (Linux), but upon changing to a new measurement computer, I can no longer connect to the device using Pyvisa. Here is a console log of the error, which happens whenever I attempt to connect to the device via Pyvisa:

I've been racking my brain over this for two workdays now with no solution in sight, so I thought it best to ask for help, since I'm obviously no programming genius. Thank you in advance.
