Hi,
Thanks for reporting. Most of the time I have more than one IDA instance opened I never experienced this issue (on macOS). Are you able to reproduce at all time or doesn't it work sometime and sometime not? I'm wondering if it has something to do with the event loop manager which is different on Windows.
Are you sure the qasync
dependecy is correctly installed?
QGB commented
@marc-etienne I installed qasync before.
Can you find a Win10 environment to retest this problem?

This is caused by an upstream bug in jupyter_client
(jupyter/jupyter_client#831). Using jupyter_client<6.1.13
fixes the issue. The issue should also be fixed in jupyter_client version 8.0, but it isn't released yet.
