What happens if you hit Retry?
If it gives the same error, do a refresh all previews.

Give it some time! Just wait until it is finished.

If that doesn't work, share any error message, you get in any query: You will see the orange warning icon on queries with possible issues. Open the queries, readd the error message if any. If the error message refers to another queries, open that one.

Hi, @PakAli 

To resolve slow processing with Csv.Document(Web.Contents(...)) in Power Query:

  1. Check File & Network: Test file size and download speed outside Power Query.

  2. Disable Background Preview: Go to File > Options > Data Load and disable Allow data preview in the background.

  3. Optimize Web.Contents: Use headers or authentication tokens:Web.Contents("https://...", [Headers=[Authorization="Bearer TOKEN"]])

  4. Download Locally: Temporarily save the file locally and test performance.

Hey! 

Sometimes it helps to:

  •  Just click close and apply (make sure that enable load is checked)
  • click refresh preview on previous steps in the query, such as source, promote headers, etc.
  • add CsvStyle=CsvStyle.QuotesAfterDelimiter to the options part: [Delimiter=",", Columns=3,  Encoding=1252, CsvStyle=CsvStyle.QuotesAfterDelimiter]
