Data file damage after installing the latest patch, unable to create backups, Validate required

After having installed the latest patch, R 58.14, from a One Step Update prompt, I recorded a few new transactions into a new account register.

When closing down Quicken at the end of the day I received error messages "Unable to create backup" (or similar) and managed to close Quicken without new backups (both Automatic and Manual) having been created.

Next morning I started Quicken and, before doing anything else, I ran a regular Validate. The Data_log.txt file showed the following errors:

QDF:
Incorrect file size.
Validating your data.
Quicken repaired Capital One CD xxxx account. No action required.
Quicken found an invalid transaction record and removed it. "Capital One CD xxxx" 0/ 0/1900
Quicken found a damaged scheduled reminder and removed it. Please check your scheduled reminders by going to Tools>Manage Bills and Income Reminders.

After Validate completed Quicken ran OK and, at the end of the day, it was able to create backups again, both a Manual and an Automatic Backup, as configured in Backup Settings ("every [1] time").

Reviewing the account register, I noticed that the Opening Balance transaction was missing.
Also missing was a Scheduled Reminder which I had entered to remind me of the CD's maturity date, 9/4/25.
I reentered both the OB transaction and the missing reminder.

Having seen similar discussions in the Community about data file damage after installing a software update I'm beginning to wonder if said damage occurs because Quicken does not properly close the data file before the task is terminated and starting the patch update process.

In a discussion with @Quicken Janean earlier this morning I mentioned this problem and I'm asking:
Can someone please pass this on to the programmers for research?
IMHO, it's extremely important to ensure that the Quicken data file is properly closed before terminating Quicken and starting the patch update process. To prevent data file damage all changes to the data file must be written back to disk including any updates to the internal file system and folder structure before one can terminate the Quicken task.

Thanks for listening.
