@Zakary Kurzawski Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
I see that you are encountering the error Failed to start a new language worker for runtime
after deploying your Azure Function App.
- Which runtime stack are you using (.NET / Java ) ? And what is its corresponding runtime stack version you are using ?
- Could you please confirm if your Function App works fine locally (before uploading to Azure) in your Dev environment ?
- Please let us know if your Function App is within VNET ? If Yes, ensure that you have followed the below articles:

There are similar issues reported in the past. I am sharing those threads also here if that helps:
