Getting an issue where google cloud deploy says the default app engine is not existing

ERROR: (gcloud.functions.deploy) ResponseError: status=[400], code=[Ok], message=[Default service account ‘@appspot.gserviceaccount.com’ doesn’t exist. Please recreate this account or specify a different account. Please visit https://cloud.google.com/functions/docs/troubleshooting for in-depth troubleshooting documentation.]

This error comes from attempting to deploy a new version of a google cloud function that is already up and running. Throughout this entire process, that specific service account is Enabled and existing on the Service Accounts tab. Attempts at other service account creations have been made with many roles like ‘Editor’ and ‘Service Account Admin’, however these simply say invalid permissions.
