I restored a backup and there are transactions missing from 2 of my accounts

My hard drive was replaced last week. I reinstalled Quicken and restored my most recent backup without any issues. All my bank and credit card accounts that I download & reconcile are fine. There are 2 accounts that are missing transactions. One is a bank account I use for a few transactions every 5 years, so no reason to connect it. The only entry is an opening balance as of today's date. The balance shown is prior to the one transaction I had in September. There should be prior transactions from 2019-20 as well. Fortunately I was able to download them all from the bank but I've lost all my details. The other is where I record all my cash spending. Every deposit to or withdrawal from my bank is automatically recorded here, then I make an entry at the end of each month where I split all my cash transactions for the month. All of these monthly entries are missing for 2024. I just got them all caught up earlier this month and backed up before giving the computer to the IT guy.

I've restored backups all the way to July and these transactions have been missing all along. It appears to be just ones that were manually entered, not reconciled with an online account. Is there a setting or something that will make Quicken include these transactions in the future? There is no possible way for me to recreate my cash expenses for the whole year, but I don't want to face this in the future.

Along with the new hard drive I changed from Windows 10 to 11. Quicken:

Are you sure that the account register(s) with the missing transactions are properly sorted by Date and are NOT filtered to only show transactions within a certain Date Range, e.g., "This Year" instead of "All Dates"?

If they are indeed missing, are you sure you haven't, at some time in the past, created a Year End Copy to truncate your current data file's transactions and eliminate transactions older than xx/xx/xx from your current data file?

Did you have crashes while working with Quicken?
If so, have you run Validate and Supervalidate to check your data file for structural errors?
