Cannot import QFX file immediately from HSBC download

Quicken for Windows 10 (Canada)
Year: 2019 Version: R22.15 Build: Edition: Canada
Browser: Firefox version 72.0.2 (64-bit)
Windows 10 Home Version: 10.0.18362 Build:18362

With Windows Quicken (Canada) open, I log in to HSBC and download transactions for Quicken. When I select 'open with Quicken Windows', previously, transactions would automatically import, but now a pop-up displays whether to 'close current file - yes or no'. Since I'm in the file I want to update, I select no, but nothing happens. If I select yes, the file disappears and I get a pop-up with the error 'Unknown error in opening data file - OK'. When I click OK, the file reappears and 'one-step' update runs, but no transactions are imported. In order in import the transaction, I now have to save the downloaded QFX file, and then manually import from inside the program File > File Import > Web Connect (.QFX) File.... .

Why do I now have to go the extra steps to save the QFX file and then import it?
