Using Python 3.11 on Windows 11. Upgraded Bokeh from 2.3.3 to 2.4.3 leaving everything else the same. Bokeh plots no longer appear.
In Firefox console get:
Uncaught ReferenceError: Bokeh is not defined
<anonymous> file:///C:/git/hosttools/python/maxwell_dm/test.html:9
This is the HTML it is complaining about
<script type="text/javascript">
Bokeh.set_log_level("info");
</script>
I get the same problem with a fresh install of Python 3.11.1 and Bokeh 3.1.0.
