Getting error when controlling SignalVu software using Anaconda Spyder Python 3.9

Hi,
My test scripts used to run fine using older versions of Anaconda3 Spyder Python development environment.  Recently I switched to a newer version of Spyder (5.4.3), and I started getting the VISA error stated below.  The address stated on the OSError line is not always the same:

 File ~\Anaconda3\lib\site-packages\pyvisa\ctwrapper\functions.py:2337 in read
    ret = library.viRead(session, buffer, count, byref(return_count))

OSError: exception: access violation reading 0x000000001766C950

Has anyone seen this before and how can it be resolved?

Hi Sarmad,

I don't believe this is a problem with SignalVu but more with your Python installation.

Do you get the same error if you call pyvisa on a bare Python installation from the terminal?
