MATLAB Crash when using connect() of Instrument Control Toolbox

Hi,

when trying to connect to my Tektronix Oscilloscope via USB, TekVISA and a Matlab Instrument Driver Matlab crashes:

deviceObj = icdevice('Tkdpo2k3k4k.mdd', 'USB0::0x0699::0x040B::C021803::0::INSTR');
connect(deviceObj);

Crash report is attached. Most important line is:

EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0000000006873fd1, pid=12244, tid=0x00000000000028ec

I'm running R2019b on Windows 10 Enterprise. Is it a problem with my code/driver or Matlab or Windows?

Thank you for answering!
