QuickBooks Desktop Extreme Lag

We use QuickBooks Enterprise Desktop 2023, and starting Sunday (07/27) we started seeing extreme lag in being able to login. 10 minutes or more.  Not unique to login, as the lag exists on internal actions and close/logout.  Initially the problem was only on the host for our company file, and not desktop clients.  The next day, we started seeing the same issue on desktop clients.  We realized that at first the update R16 v36 was not present on the clients, and then it automatically applied overnight, at which point the problem existed on all installations of QuickBooks.  

We have multiple company files, and realized this problem only occurred in one of them.  Analyzing SDK log files, it appears that the lag is occurring at points in which the AvaTax plug-in is being processed.  That matched in that the only company file with the issue is one where AvaTax is being used.  

We have support cases open with both Avalara and Intuit.  Intuit provided the guidance to update to 2024 as the problem had not occurred there.  With no other options, we did so, and have found the problem to exist on 2024 as well.  However, we have found that if we install using the latest download executable, this puts us at R15 v29, and the issue does not occur.  Only when updates are applied that brings the release up to R15 v69 does the problem recur.  

Has anyone experienced the same issue and found a different workaround / solution?  We are good until automatic updates apply, which can't be disabled as has been discussed at length in other discussions.
