Hi @MBlackburn,
Could you please share more details about the error message on your side?
Could you please share a bit more about the data entity? Is it a CDS Entity or a Dynamics 365 Entity?
The user @bishoy has faced same issue with you, please check the following thread:
https://powerusers.microsoft.com/t5/General-Discussion/Powerapp-save-new-entity/td-p/43351
I think this issue may be retricted to your data entity, please check if you have enough permission to perform the "Save" operation within your data entity.
If the data entity is a CDS entity, please check if you have been assigned to a security role which has enough permission (e.g. Editing, Creating, etc) to access the CDS entity.
More details about managing CDS entity permission, please check the following article:

Best regards,
