# Sage crashing on Notebook startup

I've installed SageMath 9.3 on Windows 10 using the Windows Installer available on github. However, every time I start a notebook, it crashes. (Side note: I have successfully installed and used SageMath on another computer.) I've tried opening a notebook by running "SageMath 9.3 Notebook" from the start menu, and also by typing the command "sage --notebook=jupyter" from the SageMath 9.3 shell. Both of these open Jupyter in my browser. But when I try to open a SageMath notebook, I get the following error in the shell:

[W 11:44:21.592 NotebookApp] 404 GET /nbextensions/jupyter_jsmol/extension.js?v=20220329114408 (::1) 12.30ms referer=http//localhost:8888/notebooks/OneDrive%20-%20University%20of%20Ottawa/Sage%20notebooks/Representations.ipynb /opt/sagemath-9.3/src/bin/sage-python: line 2: 2473 Illegal instruction (core dumped) sage -python "\$@"

(sage-sh) Savage@Savage-STEM:~\$

Unhandled SIGILL: An illegal instruction occurred. This probably occurred because a *compiled* module has a bug in it and is not properly wrapped with sig_on(), sig_off(). Python will now terminate.
