It is incredible that as of Aug 16, 2021 Turbo Tax (Intuit) still did not fix this problem with asking activation multiple times on the same machine.
It happened to me again last week and then I found out that there was a USB flash drive connected.
I removed it and T.T. then came up fine.
At first I thought it was because I updated to Windows 11 (Insider Build), but clearly that was not the case.
