Answer 1

@SPBP It looks an error with CORS setting on your storage account. Could you please check if you have enabled CORS on the storage account as mentioned here along with the required access before reopening the studio to access NER?

Enable CORS for your storage account Make sure to allow (GET, PUT, DELETE) methods when enabling Cross-Origin Resource Sharing (CORS). Set allowed origins field to https://language.cognitive.azure.com. Allow all header by adding * to the allowed header values, and set the maximum age to 500.
