Assertion error Matlab R202b

Dear,
Currently I am using Python to request some data from Matlab. I perform this by first enabling the shared option with Matlab using:
matlab.engine.shareEngine()
Following this I attempt to connect with matlab inside Python using:
try:
findSes = matlab.engine.find_matlab()
eng = matlab.engine.connect_matlab(findSes[0])
except EngineError:
eng = matlab.engine.start_matlab()
This usually works, but somehow it sometimes can't connect which results in that the script does not execute. Another error which exists is the following one, which appears in the Python kernel:
Assertion failed: frame‑>index() == index
Function: unsigned __int64 __cdecl foundation::msg_svc::transport::layers::message::Message::append(class std::unique_ptr<class foundation::catapult::carrier::framing::Frame,struct std::default_delete<class foundation::catapult::carrier::framing::Frame> > &&), file b:\matlab\foundation\message_services\transport\layers\message\message.cpp, line 149
I hope someone could assist me on how to solve this error.
Thanks

I am not sure what you're trying to do though, one of the most frequent mistakes peopel make is data type incompatibility.
You should specify the data type as follows:
try:
findSes = matlab.engine.find_matlab()
eng = matlab.engine.connect_matlab(double(findSes[0]))
except EngineError:
eng = matlab.engine.start_matlab()
