Problem with connecting several HW-instruments using visadev

I'm trying to connect several hardware instruments to MATLAB using visadev. The first instrument I connect works properly, but when I try to add a second I get an error. The code I'm using looks like this.

>> pm = visadev('GPIB0::20::INSTR')

pm =

GPIB with properties:

ResourceName: "GPIB0::20::INSTR"

Alias: ""

Vendor: "Rohde&Schwarz"

Model: "NRP2"

BoardIndex: 0

PrimaryAddress: 20

SecondaryAddress: 65535

NumBytesAvailable: 0

Show all properties, functions

>> pm2 = visadev('GPIB0::23::INSTR')

Resource string is invalid or resource was not found.

Both instruments are connected and show up in Keysight I/O. If I clear the first instruments (address 20) then I can connect the other one (23) without any issues.

Thanks in advance!

Update: Installed MATLAB 2022b and now it is working without any issues.
