Extension Publish Error failed with code UnprocessableEntity

Everything was working fine on Wednesday but when I try to publish and debug an extension from Visual Studio Code to the Cloud Sandbox this morning, it’s failing with:-

The request for path /v2.0/sandbox/dev/apps?SchemaUpdateMode=synchronize&DependencyPublishingOption=default failed with code UnprocessableEntity. Reason: You do not have the following permissions on TableData Published Application: IndirectInsert.

I’ve tried various extensions and they’re all failing, but were working on Wednesday. No changes in between?

Any thoughts?
