Can you help with installation based oin facts below?

Started having issues with unknown accounts showing up on account listings (just unknown totals with no other info). I would just delete them as they are a minor inconvenience. Then they would double entry. Then the quicken application would open to the password screen and after entering I got the spinning wheel and a windows end process box. I have since downloaded new version win 2020 ver. R25.21 build 27.1.25.21 twice and I get the same result.
