Hey @thejohnrainwater, thanks for reporting. Some people have reported this problem already but we still don't know why it's happening.

Would you be willing to help us track the cause of this problem in the Spyder code?

[thejohnrainwater]

Sure but I’m traveling today I could do it tomorrow John

Great! These are the steps you need to do follow:

1. Open this file in Spyder or another text editor:

   C:\Users\Admin\AppData\Local\spyder-6\envs\spyder-runtime\Lib\site-packages\spyder\app\mainwindow.py
   

2. Go to line 788, which should appear like this:

   spyder/spyder/app/mainwindow.py

   Lines 785 to 791 in 49a9cca

   	try:
   	if attr in self._INTERNAL_PLUGINS_MAPPING.keys():
   	return self.get_plugin(
   	self._INTERNAL_PLUGINS_MAPPING[attr], error=False)
   	return self.get_plugin(attr)
   	except SpyderAPIError:
   	pass

3. Change there error=False to error=True.

4. Close Spyder (if you have it open) and start it again.

5. Do the same things you did before that generated the error.

6. Clicking on the Show details button of the window that shows up after the error appears and copy/paste its text here.

Thanks again for your help @thejohnrainwater!
