Can't use simultaneously Rx and Tx of Lime in Pothos

I’m trying to run Pothos examples from LimeSDR_Workshop. All work fine except LimeTxRxDemo.pothos . In Message Window it show
SoapySDR: ConnectionSTREAM: Cannot claim interface - Resource busy
I think this error appear when I use Tx and Rx simutaneously because when I disable one, the error disappear.

Anyone can help me to fix this problem ? Thank you a lot

I found the problem is source and sink are in different processes
Just change “affinityZone” : “gui” -> “affinityZone” : “” then it works
