Lost link to Coastal FCU after last update

Question

After the last update Quicken stopped updating my Coastal FCU accounts.  I did all the usual stuff - I deleted the service, then reinstalled it.  I reset the account, no change.  I restored a backup copy, same problem.  This is not an issue of Covid19 - the update runs but does not bring any transactions.  No error messages or anything.
 there are some  translation issues too - when I tried to re-establish the links, Quicken brings all my checking transactions into a money market fund.  I assure you I did the links properly, and I did it twice to make sure.  Also if I try to cut/paste my password into the Download screen, it opens a box that says Void Current Transaction?  This occurs even when there is not an unsaved transaction or anything.

If you had read my reply  you would see that I have rebooted, more than once in fact.
 I tried to validate, it locks up the entire computer.  Have to use task manager to shut it off.  then re-boot.
 Now there is a new problem - Quicken has now wiped out my password vault.  When I try to update it asks for the password for every account I have.
 I restored an earlier version and now the vault is wiped clean.
 I am going to delete this wonderful program and try a re-install.

If you haven't
rebooted Windows since you installed the latest software update, please do so
now and then try Quicken again.

Still not working?

Let's try some
"Troubleshooting 101" to ensure the Quicken software is installed and
updated properly and that your data file is in good working order.

Please perform all the steps in this document in the order specified:

If that still doesn't do the trick and if you haven't done
so already, I'd say it's time to call Quicken Support on the phone and request
help.  Let them do a screen share session
with you to review a download log file on your computer, to determine the nature
of the problem and to figure out how to fix it.

1. Thanks for the tip about the Setup for Cut/Paste.  I have no idea how this was changed, because it worked fine in the past.

2. Quicken Premier 2020, R26.15
 Windows 10 Pro update 1909 (updated in Dec)
 NO error codes or messages.  Symptom - as described in my original question -  Quicken doesn't appear to be linking to the correct accounts.  And when it downloads transactions, it believes everything has downloaded properly although there are no new ones.
 Bank - Coastal FCU
 Accounts - Checking and MMF, that I can tell for now
 When occurs - one step update.
 What have I done - as I said in my original post - I have tried deleting then re-establishing the links; resetting the accounts; re-starting the PC; restoring a prior copy.  None of these have worked.

Everything was OK until the last Quicken update.  I would roll it back if I knew how.
