Why is Quicken crashing the past 6 (?) weeks?

Quicken crashes in the middle of posting a transaction, reconciling a statement, and no consistent reason. I spent 1 hr 20 mins on the phone last week and shared my screen with the agent. No apparent cause. We uninstalled and reinstalled Quicken. It worked for 10-15 minutes and intermittent crashed again. I bought a new laptop (thinking it was my computer) and the only program I installed was Quicken. It still crashed. There is clearly an issue with your update or the interaction with Windows 11. THOROUGHLY FRUSTRATED!!!
