Hi,

Please help with the following issue. Thanks in advance

OS: Windows 11
Gnuradio version: 3.8.3.0 
(Python 3.8.0)
Source: radioconda 2021.04.08

Observation: FLow graph starts, output windows appear and stops in a fraction of second.

Error: 
gr::pagesize: no info; setting pagesize = 4096
Traceback (most recent call last):
