I just spent 20 minutes replying in detail, only to have this ridiculous forum delete it, apparently because I was no longer logged in. Then I go to log in, and the forum wants 2FA to log in to a FORUM??? Come on. Fix QB software before worrying about 2FA on a technical support forum.
Back to the problem:
I verified and rebuilt the company file (for the record, I had previously done that, but did it again, following your instructions). Did not help.
I downloaded and ran the various Fix It tools, including the File Dr., not mentioned here. Did not help. (And, I note that there were references to Visual Studio C++ libraries from 2012 and 2013. Much has changed with MS compilers. Why is QB using versions 10 years old??).
I even tried loading a recent backup file, and reconnecting the account. Same problem. Chart of Accounts says the account is linked to the bank (based on icon in the account list) but the account does not appear on the list of accounts in Bank Feeds Center. Return to Chart of Accounts, edit the bank account, and Online Services for the account are deactivated. Go to the Bank Feed Settings tab, click the button to enable, get a message "You must enter a value for all of the fields on the Online Services tab." Where is the Online Services tab??? On the Bank Feed Settings tab, the Account Customer ID field is empty. I enter the Customer ID provided by the bank (which is NOT the company tax ID) and a message appears saying the ID must be in the form of a Tax ID. Enter the company Tax ID, and back to the "You must enter ..." message. When I finally give up in frustration, click the "Deactivate..." radio button, and then "Save & Close", QB CRASHES - nothing but an intervening pop-up asking whether to send the report. I have allowed that once, with no response from QB.
One additional observation, which SHOULD be irrelevant but...
When this fiasco started, against my better judgement I allowed QB to update itself. When I attempted to open the company file after the update, I was prompted to create an online account. I did not do so (I selected the delay 7 days option). I have no interest in an online account - that is why I have desktop software running on a local machine which can be easily isolated when doing anything that does not require internet access (such as getting bank transactions).
That said, what else can I try?
