Just to give you guys an update:

Over all I must have spent 40 to 50 hours on my own and with QB support staff to get to the bottom of the issue. QB support staff did regular follow-up and was in touch with me almost every day to see if his suggestions worked or not. Since this was random crash, I had to use QB sometime to see if it would crash or not. He did good job. Much better than the last guy who said that QB Desktop Pro 2021 is out of support and he could not help me.

He basically repeat same steps I had already taken - repair my QuickBooks installation, uniinstall/reinstall, verify data, rebuild data, run QuickBooks Desktop File Doctor, run QuickBooks Tool Hub, etc.... Steps that I had already taken.

He also had me create new Windows login account on my computer and see if operating QB under that new login would solve the issue (it did not). He then had me install QB on another computer and see if that would help (it did not).

Then, finally he asked me to collect all kinds of logs and told me that there are other users also reporting this issue and QB technical team will evaluate the logs and update me.

Which leads to this question - if QB technical support team knew that there were others reporting this issue as well, then why make me go through all repair/reinstall steps, testing on different computer under different login account, etc.?
