I already replied to this one but it never showed up. Figures.

Seeing this issue as well with Win10/11 machines. It is 100% a problem with QB. Event viewer shows it crashing, then Chrome, Office Suite, or other random programs will crash all with the same NTDLL fault code of heap corruption.

QB has a memory issue and they need to fix it, soon. Happy to offer whatever event logs or other logs Intuit wants, but I'm not spending 6 hours on the phone disabling my firewall and clearing my cookies.
