I ran your LTspice file but got an oscillation. Did you change anything in Simulate > Control Panel > SPICE ? (I Reset to Default Values for this test). LTspice and Qspice may have different simulation option (compare .option) which can introduce different.
For QSpice, if you add .options method=gear, it can eliminate oscillation in your circuit. However, Mike’s gave a warning about using Gear method, refer to this post for reference.
