I have used the chat and talked to Intuit. The only point they had that my computer did not have enough memory to run Quickbooks Desktop Pro 2022 R4. I have installed this new version of Quickbooks on a gaming desktop with 16 GB of system ram and Windows File explorer keeps still crashing, when I use Quickbooks.
