Soapy SDR Source Problem in Pothos Flow - Please advise

[ngriesert]

I am new to Pothos Flow and SoapySDR. I have an RTL-SDR V3. I am able to use both SDR# and Cubic SDR with my RTL-SDR. When I place the Soapy SDR Source in the Pothos FLow environment the SDR is found and recognized, but not usable.

I have been unable to find a resource that suggests what is wrong or what I should try to remedy the problem. Does anyone have any feedback on what the problem is? The problematic id here is: "SoapySDR: rtlsdr_get_device_usb_strings(0) failed" I don't know what to check...

Here is the log in the message Window of pothos flow:
