I am the original poster. I have spent hours troubleshooting on the desktop. Tier 1 phone support, although helpful during a two hour consult, did not cure my issue. It went away for only the one evening. Next day it was back.

Like another poster in this thread, if I pull the ether net before launch, I can get some things done.

I can and have used all the tools in the Tool Hub on the lap top (Intel) but cannot use File Doctor on the desk top (AMD). That is weird on it's own. There is no issue with my QB file as it runs fine on the lap top.

On the desk top I have even re installed Windows and QB Pro 2021 and still get the unrecoverable errors. So I was forced to buy a new lap top.

Next time I open QB on my desk top PC I will post the UN-recoverable error number. Or numbers if I am hard headed and determined to make it work. If more than one number occurs when it decides to error out on subsequent tries. Error logs, dump files whatever. Let me know what may help fix this.

EDIT:

Reminder that all was well until a QB update sometime mid June. Whenever the June program update came through.
