Quicken R31.12, Build 27.1.31.12. Windows 10 20H2, OS Build 19042.476. I entered transactions into Quicken and then validated my file. An account index was rebuilt (it did not say which) no action needed. I validated the file a second time and a category was removed (no indication of what category. I had to go back and restore my 1-31-2021 backup file as all the the files from 2/1/2021 to 2/08/2021 produced the same errors.
I restored the 1-31-2021 file and downloaded all of my credit card, bank transactions with no problems. The file validated OK. I saved a backup of the file.
Now I had to redo my January investment statements (which I do manually) of which there are three. I tried to do investment account #1. I was entering a stock purchase and when I pressed Enter, all of the transactions disappeared.
I attempted to validate the file and it was corrupted. I renamed that file and restored from the backup I had made before I started on the investment accounts. This time I started with Investment account #2. Again while entering a stock sale Quicken just quit.
I attempted to validate that file and it too was corrupted. Rename file and restore again from the backup. I tried starting with investment account #3 this time. Again when I pressed enter for a sale transaction all of the transactions disappeared. (see first screen shot)
Restored again. This time investment account #1 reconciled normally. Backed up the account, then validated OK. Repeated with investment account #2, transactions disappeared. Restore backup then account #2 reconciled OK. Then investment account #3 reconciled OK. This took 3 hours this morning.
What is going on to cause this?
