Every time there is an execution error, the Jupyter Notebook crashes without showing the error on the notebook, but showing it on the Jupyter prompt.

It forces me to restart the notebook and execute all the cells each time.

Screenshot of the Notebook freezing when writing an error

[IPKernelApp] ERROR | Exception in message handler:

During handling of the above exception, another exception occurred:

Hotfix

This doesn't solve the problem, but it provides temporary fix for the problem. It allows to show the bug/execution error without crashing the notebook

import traceback
try:
   1+"letters"
except:
   traceback.print_exc()
