Hi @PaladinoL
Thanks for posting your question in the community!
Hopefully, I can help you here! Here is a document that shares what Error 5 might mean for you. - https://help.webex.com/en-us/WBX59/Error-Error-5-Setup-was-unsuccessful#:~:text=I%20receive%20an%20error%205,are%20timing%20out%20when%20downloading.
I'm not sure if this applies to your issue, but it seems there may be a limit to how many meeting templates one can create. You can access your meeting templates and edit them by logging in to your Webex site. Switch to Classic View. Under the Webex Meetings Tab, click the Setup dropdown. Click on Preferences. There will be a dropdown for Scheduling Templates. Click that and you should see a list of all of your meeting templates. Here you can erase/edit any templates you have. Screenshot below.

Let me know if this helps, and feel free to ask any other questions you may have.
Thank you for all that you do for your students. Wishing you the best on your first day back teaching!
