From the error output it doesn't seem to be generic ROS issue, but instead application specific one. Maybe asking on the package's forum may get more attention esp. from the developers of the package (although asking on this answers forum is perfectly fine, many developers may not be paying attention).

I had this issue on a different custom rqt, the problem is that in the constructor I was calling a service (without timeout) that was not available, therefore the rqt just seemed stuck and with no log info that informed about what was going wrong. So my advice is to check the code inside the rqt constructor and search for blocking functions (such as service calls without timeout).

That doesn't help solve the error
