Channel crashing on hitting ECP command /query/sgnodes/all

I am testing a channel on Roku and i was using ECP commands to get the nodes and their attributes and it was working fine.

But now when I hit the ECP command http://192.168.xxx.xx:8060/query/sgnodes/all I get the below error

<?xml version="1.0" encoding="UTF-8" ?> 1702287782916 dev FAILED query-sgnodes command exception: Plugin RPC event timed out

PFB the screenshot.
