I had this problem when working on my 2020 return so it was not fixed after 2019.
For me the fix was simple - I had a flashdrive in a port - unrelated to TurboTax but it doesn't seem to matter. As soon as I safely removed the flashdrive, TurboTax opened up and I could continue my return. Many people store their returns on a portable flashdrive - I suggest you store it on the computer harddrive until you are finished. Hope this works for others.
